Introduction
The Plastics Compendium Volume 2, Comparative Materials Selection Data INTRODUCTION This volume of The Plastics Compendium contains essential information for designers, engineers and material specifiers working with plastics. It provides comparative data in a format designed to facilitate the selection of materials for given applications, on the basis of processability and performance. The information is based upon value judgements (rankings) which have been assigned to 62 of the principal qualities of 351 generic and modified plastics material types. These materials encompass thermoplastics, thermosets and thermoplastic elastomers, and are representative of 30,000 or more commercially available trade named materials.
BACKGROUND The judgements which form the basis of this volume were made by a panel of independent experts in plastics technology, and were compiled originally for use in PLASCAMS, Rapra Technology’s Plastics Computer Aided Materials Selection software. The judgements were based upon information from a variety of sources, including published data (research reports, company literature, etc.) and the knowledge and experience of the panel. The information has now been published in hard copy format as The Plastics Compendium, in response to requests from many of the 1,000 clients who have rented the software over the last 13 years. Within PLASCAMS, 10 ranking values are used, between 0 and 9. These have been simplified in this volume of The Plastics Compendium, so that each material/property combination has been assigned one of 6 descriptions, ranging from not applicable (where a material does not possess that property) to excellent. The descriptions assigned in The Plastics Compendium and their equivalents in PLASCAMS are as follows: The Plastics Compendium

CONTENT AND FORMAT This volume contains two main sections: ●
Property based listings,
●
Comparative materials data sheets.
The 62 property based listings, in the front portion of the book, each contain a textual description of the property, followed by lists of all those materials categorised as excellent, very good or good. The property texts outline the principles underlying the assignment of the comparative descriptions. In
xix
The Plastics Compendium - Volume 2, Comparative Materials Selection Data most instances it will be clear whether an excellent rating indicates a high or low value of a particular property. However, for some properties, either a high or a low value may be desirable according to the mode of use, and thus it is important that you consult this explanatory text in order to be clear how the descriptions have been assigned. As a general rule the property title indicates the order of assignment. For example, in the case of toughness, a material described as very poor is not very tough, i.e. it is brittle, whereas a material described as excellent will be extremely tough. A not applicable description indicates that a material does not exhibit a property at all. For example, in the case of transparency, an inherently opaque material will have been assigned the description not applicable. Similarly, in the case of a manufacturing process such as structural foam moulding, any materials which cannot be processed in this way at all have been described as not applicable. In a few instances arbitrary decisions were made regarding the order of assignment. For example, in the case of friction, very low friction is described as excellent and very high friction as very poor. The property texts also contain a basic definition of the property, or an explanation of its significance. The second section of the book provides 351 comparative materials data sheets, i.e., one for each material, providing a full listing of the descriptions assigned for all 62 properties. This layout permits easy comparisons, and a methodology for materials selection based on this comparative data is presented below. Additionally, if a material has already been specified for a particular process or application, reference to the comparative materials data sheets may show at a glance where any problems are likely to arise. A large number of abbreviations are commonly used to describe plastics. Many of these are used in The Plastics Compendium, and a list is provided towards the end of this introduction.
MATERIALS SELECTION METHODOLOGY The selection of a suitable plastic material for a particular application must take account of a number of factors. These are likely to include the following: ●
The operating environment experienced by the component, e.g. exposure to extremes of temperature, mechanical forces, fire, radiation or electrical charge.
●
The primary production method, e.g. moulding, extrusion, pultrusion, forming, etc.
●
Assembly technique - Must the component be bonded, welded or fastened mechanically?
●
The cost of the material.
●
Aesthetic and decorative features - Is surface finish important? Must the component be transparent? Will it be painted or plated?
Generally, all of these factors needs to be considered simultaneously in order to obtain a material that satisfies each of the requirements to some degree. However, in some cases a material may be selected which has exceptionally good properties in just one or two areas. One such example is provided by PTFE, where its difficulty in processing and low strength and stiffness are tolerated or designed against, in order to utilise its exceptional chemical resistance.

Introduction When making a materials selection there are usually a number of material requirements that are essential and a further group that are desirable. Essential requirements are likely to be defined by the operating environment, or by the availability of primary production methods, or perhaps by specific end-uses, such as a need for transparency. Desirable properties may be selected on the basis of preference or compromise. A factor such as low material cost may be essential for a bulky, mass produced item, but inconsequential for a small, specialist component. A rational materials selection procedure must accommodate both the essential and the desirable criteria. The first stage must be to identify those materials which demonstrate the essential qualities to the required level. All materials which fail to meet these requirements may be eliminated from further consideration. The second stage is then to order or rank the selected materials with respect to certain other desirable qualities, and thus obtain a short list of candidate materials which is suitable for detailed scrutiny. Volume 2 of The Plastics Compendium has been arranged in a fashion which facilitates this two stage approach to materials selection. The property based data in Section 1 allows materials to be selected or eliminated on the basis of 62 primary material properties. These are grouped under 4 general headings: ●
General and Electrical.
●
Mechanical.
●
Processing.
●
Post-processing.
An alphabetical index to these properties is provided on page 489. For each property up to 3 lists of materials are provided, containing all those materials which have been categorised as excellent, very good or good, as defined above. By consulting these lists it may be possible to identify a set of materials which meet all the essential requirements. An ideal set of materials would all be rated as excellent for all the essential properties. Common sense and experience will assist in the definition of those properties for which excellence is essential, as against those for which a very good performance might be adequate. The property descriptions provided on these pages will also provide guidance. The set of materials identified using Section 1 may then be refined or ordered using the materials based information contained in Section 2. A comparative data sheet is provided for each of the 351 materials. This rates the material’s performance against all 62 property criteria, and highlights the extremes of behaviour. Thus desirable qualities or preferences may be compared for all the materials identified by the initial selection procedure. The final short list may be ranked according to how many of the desirable property requirements have been met. A brief list of common applications is also provided for each material, giving a further indication of suitability. Additional information about the short-listed materials can be obtained by referring to The Plastics Compendium - Volume 1, Key Properties and Sources. This provides descriptive text on the strengths and, in particular, the weaknesses of the same 351 generic and modified materials, together with numerical datasheets.
Please note: Prior to the final selection and use of any material, it is strongly recommended that the material’s suppliers are contacted for advice as to the suitability of their specific grades for the given application.

The Plastics Compendium - Volume 3, Time and Temperature Dependency Volume 3 will contain information regarding the long term performance characteristics of plastic materials. In particular it will cover modulus as a function of time and temperature, and long term failure characterisation. This will provide basic long term design data essential in the primary selection of plastic materials for engineering applications.
Chemical Resistance Data Sheets - Volume 1, Plastics (Second Edition, 1993) Volume 2 of The Plastics Compendium provides comparative data for detergent resistance and hydrolytic stability. However detailed information on resistance to a wide range of chemicals is clearly beyond its scope. This information is provided by the Chemical Resistance Data Sheets - Volume 1, Plastics, also published by Rapra Technology Limited. This edition provides qualitative assessments of the resistance of 44 plastics to 190 chemicals, as well as quantitative data for a smaller set of materials and environments.
PLASCAMS Computer Aided Materials Selector PLASCAMS is the leading independent PC-based materials selection package covering thermoplastics, thermosets, composites and thermoplastic elastomers.

Arc Resistance
General and Electrical Properties Arc Resistance The arc resistance of a material is the time taken for a conductive path to develop on the surface as the result of an arc passing between electrodes placed near the surface. Good arc resistance is necessary in conditions where high voltage discharges are unavoidable. Arc resistance is reduced by fire retardants. Arc resistance is highly dependent on the particular grade of material and this volume therefore ranks those materials that are inherently good or inherently poor. Therefore the advice of the raw material supplier should be sought to determine the optimum grade of any material. An excellent rating indicates excellent resistance to arcing. A very poor rating indicates poor resistance to arcing. Not applicable indicates that the material is conductive. The following tables list only those materials which have been assigned a rating of excellent, very good or good for arc resistance, which may be appropriate for use in high voltage applications. To further evaluate the processability and performance of any of the listed materials under the desired conditions, refer to the complete comparative data sheets provided on the pages indicated below.

General and Electrical Properties
Dielectric Constant
Dielectric Constant The dielectric constant of a material is defined as the ratio of the capacitance of a particular capacitor containing the material to that of the same capacitor when the material is removed and replaced by air. When designing a capacitor it is desirable to include a material with a high dielectric constant as more power can be stored in a given volume. Conversely, materials with low dielectric constants are preferred for applications involving high frequencies to minimise electric losses. The dielectric constant varies with frequency and generally increases with temperature. The ratings are based on room temperature values. An excellent rating indicates a low dielectric constant. A very poor rating indicates a high dielectric constant. Not applicable indicates that the material is conductive. The following tables list only those materials which have been assigned a rating of excellent, very good or good for dielectric constant, which may be appropriate for use in high frequency applications. To further evaluate the processability and performance of any of the listed materials under the desired conditions, refer to the complete comparative data sheets provided on the pages indicated below.

The Plastics Compendium - Volume 2, Comparative Materials Selection Data
Dielectric Strength The dielectric strength is the voltage that an insulating material can withstand before dielectric breakdown occurs. The value of dielectric strength varies with specimen thickness, generally the thinner the specimen the higher the dielectric strength. When assigning rankings for The Plastics Compendium, values were based on a specimen of around 3mm thickness, at room temperature. An excellent rating indicates a high dielectric strength. A very poor rating indicates a low dielectric strength. Not applicable indicates that the material is conductive. The following tables list only those materials which have been assigned a rating of excellent, very good or good for dielectric strength. To further evaluate the processability and performance of any of the listed materials under the desired conditions, refer to the complete comparative data sheets provided on the pages indicated below.

Gamma Radiation This quality is an assessment of the resistance to gamma radiation. In assigning a rating greater emphasis has been placed on changes in physical and mechanical properties than changes in colour, as in many cases for low dosage (e.g. sterilisation) any colour changes are reversible. An excellent rating indicates excellent resistance to radiation. A very poor rating indicates poor resistance to radiation. The following tables list only those materials which have been assigned a rating of excellent, very good or good for resistance to gamma radiation. To further evaluate the processability and performance of any of the listed materials under the desired conditions, refer to the complete comparative data sheets provided on the pages indicated below.

General and Electrical Properties
Maximum Operating Temperature
Maximum Operating Temperature Maximum operating temperatures are based on the Underwriters Laboratory (UL) rating for the long-term (100,000 hours) ability for a material to sustain mechanical, electrical and impact loads. Specifically the UL temperature is defined as that temperature which causes the tensile strength of the material to fall to half its initial value after exposure of 100,000 hours. In cases of short term exposure, say up to a few hours, which would include sterilisation by autoclaving (typically 30 minutes at 134°C / 270°F), or paint drying (say 20 minutes at 140°C / 285°F), then decisions taken on the basis of maximum operating temperature may not be the most appropriate means of selecting candidate materials. For short exposure times there may not be any significant level of oxidation or other chemical change in the material that would lead to a loss in mechanical or physical properties. However even short exposure to high temperatures can lead to loss of dimensional stability. In some cases therefore where the dimensional stability or the stiffness of the material at the maximum use temperature is more important, then it may be better to select materials on the basis of their heat distortion temperature (HDT). An excellent rating indicates a high maximum operating temperature. A very poor rating indicates a low maximum operating temperature. The following tables list only those materials which have been assigned a rating of excellent, very good or good for the maximum operating temperature. To further evaluate the processability and performance of any of the listed materials under the desired conditions, refer to the complete comparative data sheets provided on the pages indicated below.

Oxygen Index The oxygen index is the percentage of atmospheric oxygen that will just support material combustion under equilibrium conditions and therefore the higher the oxygen index the more difficult it is for the material to burn. The normal atmospheric oxygen content is 21%. As a very rough guideline: if the oxygen index of a material is less than 22% then the material will be ignited by a small flame and will continue to burn at any angle. If the oxygen index is in the range 2228% then it will burn when held vertically but it will extinguish if the specimen is held horizontally. If the oxygen index is greater than 28% then it will generally extinguish unless an external flame is applied. A rough correlation is obtained with the the Underwriters Laboratory (UL) flammability ratings: < 22% 22 - 28% > 28%
HB V1, V2 V0
The level of oxygen required to sustain combustion decreases with increase in temperature. Some materials are inherently flame retardant others can be made to be so by inclusion of chemical modifiers. The room temperature oxygen index was used to apply the ratings. An excellent rating indicates a high oxygen index. A very poor rating indicates a low oxygen index. The following tables list only those materials which have been assigned a rating of excellent, very good or good for oxygen index. To further evaluate the processability and performance of any of the listed materials under the desired conditions, refer to the complete comparative data sheets provided on the pages indicated below.

Shrinkage This indicates the inherent shrinkage of a material during injection moulding. Moulding conditions, orientation of fillers, orientation of flow and other factors can all influence the specific level of shrinkage but the inherent quality is material dependent. This is the immediate level of shrinkage. Post moulding crystallisation is accounted for by the quality ‘dimensional stability’ in the Mechanical Properties group. An excellent rating indicates a low level of mould shrinkage. A very poor rating indicates high mould shrinkage. The following tables list only those materials which have been assigned a rating of excellent, very good or good for shrinkage. To further evaluate the processability and performance of any of the listed materials under the desired conditions, refer to the complete comparative data sheets provided on the pages indicated below.

General and Electrical Properties
Tracking Resistance
Tracking Resistance The ability of an insulator to withstand surface discharge of electricity, tracking resistance (based on the KB procedure) is the electrical potential applied between two electrodes placed in contact with the surface that causes a conductive path to develop between them. Good tracking resistance is necessary in applications where surface contamination and degradation are unavoidable, for example in marine environments. Tracking resistance is highly dependent on the particular grade of material, so this volume ranks these materials with inherently good or inherently poor tracking resistance. Therefore the advice of the raw materials supplier should be sought to determine the optimum grade of any material. The presence of fire retardants can severely reduce the tracking resistance of a material. An excellent rating indicates excellent resistance to tracking. A very poor rating indicates poor resistance to tracking. Not applicable indicates that the material is conductive. The following tables list only those materials which have been assigned a rating of excellent, very good or good for tracking resistance. To further evaluate the processability and performance of any of the listed materials under the desired conditions, refer to the complete comparative data sheets provided on the pages indicated below.

Volume Resistivity The volume resistivity of a material is its resistance to leakage of current through itself. Specifically it is the ratio of the potential gradient in the direction of the current to the current density. It is dependent on, for example, moisture in the material and temperature. Typical values of volume resistivity at room temperature were used to assign rankings in this volume. An excellent rating indicates high volume resistivity. A very poor rating indicates low volume resistivity. Not applicable indicates that the material is conductive. The following tables list only those materials which have been assigned a rating of excellent, very good or good for volume resistivity. To further evaluate the processability and performance of any of the listed materials under the desired conditions, refer to the complete comparative data sheets provided on the pages indicated below.

Mechanical Properties Brittle Temperature This is an assessment of the sub-zero (Celsius) temperature at which the material becomes brittle. An excellent rating indicates a low brittle temperature, i.e. it is serviceable to low temperatures. A very poor rating indicates a high brittle temperature i.e. it only has a limited sub-zero range of usefulness. The following tables list only those materials which have been assigned a rating of excellent, very good or good for brittle temperature, which may be appropriate for use in sub-zero environments. To further evaluate the processability and performance of any of the listed materials under the desired conditions, refer to the complete comparative data sheets provided on the pages indicated below.

Friction This is an assessment of the coefficient of friction of the material in terms of the dynamic (sliding) friction against steel. It should be remembered that friction is influenced by temperature, surface contamination and, most importantly, by the two material surfaces. An excellent rating indicates a low coefficient of friction. A very poor rating indicates a high coefficient of friction. The following tables list only those materials which have been assigned a rating of excellent, very good or good for friction. To further evaluate the processability and performance of any of the listed materials under the desired conditions, refer to the complete comparative data sheets provided on the pages indicated below.

Strain at Yield This is an indication of the degree of strain that a material can accept before yielding. An excellent rating indicates a ductile material with no yield and high elongation to break. Not applicable indicates a brittle material with low elongation to break. Materials rated very good to very poor include all those exhibiting yield, ranked according to their strain at yield, as well as ductile materials with lower elongation to break than those rated as excellent, and brittle materials with higher elongation to break than those rated as not applicable. In general, ductile materials are ranged from excellent to very poor by descending elongation to break, and brittle materials from poor to not applicable, by descending elongation to break. The following tables list only those materials which have been assigned a rating of excellent, very good or good for the strain at yield.

Water Absorption This represents the tendency of the material to absorb moisture. Absorption of moisture usually results in changes in electrical and mechanical properties and also in physical dimensions. The ratings are based on the weight gain of a sample after immersion in water at room temperature for 24 hours. An excellent rating indicates low water absorption. A very poor rating indicates high water absorption. The following tables list only those materials which have been assigned a rating of excellent, very good or good for water absorption. To further evaluate the processability and performance of any of the listed materials under the desired conditions, refer to the complete comparative data sheets provided on the pages indicated below.

Compression Moulding This quality indicates the ability of the material to be compression moulded. Although it is technically possible to compression mould a thermoplastic, it is rarely done on a commercial basis for large volumes for economic considerations. For this reason a number of thermoplastics have been assigned a rating of not applicable. Thermosets which are commonly compression moulded are assigned ratings on the basis of the ease or difficulty of moulding. The factors which increase the inherent difficulty of compression moulding are similar to those for injection moulding (p.101). An excellent rating indicates that the material is easy to compression mould. A very poor rating indicates that the material is difficult to compression mould. Not applicable indicates that the material is either not compression mouldable or that it is not commonly commercially practised. The following tables list only those materials which have been assigned a rating of excellent, very good or good for compression moulding.

Injection Moulding This quality assesses the inherent ability of a material to be injection moulded. Factors which increases the difficulty of moulding include: Material handling - where particular care needs to be taken in preventing moisture absorption. Processing - if the material has a narrow melt temperature range between acceptable flow and degradation or if the material is prone to degradation. Processing - if a high mould temperature is necessary requiring oil mould heaters. Processing - if the material has a tendency to lead to abrasion or damage to the tool surface. An excellent rating indicates that the material is easy to injection mould. A very poor rating indicates that the material is difficult to injection mould. Not applicable indicates that the material is not injection mouldable. The following tables list only those materials which have been assigned a rating of excellent, very good or good for injection moulding.

Transfer Moulding This quality indicates the ability of the material to be transfer moulded. Although it is technically possible to transfer mould a thermoplastic, it is rarely done on a commercial basis with the exception of certain specialised encapsulation techniques for electronic components. For this reason all thermoplastic materials have been rated as not applicable. Thermoset materials have been rated in the range very poor to excellent on the basis of the ease of moulding. An excellent rating indicates that the material is easy to transfer mould. A very poor rating indicates that the material is difficult to transfer mould. Not applicable indicates that the material is either not transfer mouldable or that it is not commonly commercially practised. The following tables list only those materials which have been assigned a rating of excellent, very good or good for transfer moulding. To further evaluate the processability and performance of any of the listed materials under the desired conditions, refer to the complete comparative data sheets provided on the pages indicated below.

Vacuum Forming This quality is an assessment of the ease or difficulty of vacuum forming a material. It is a combined assessment of vacuum forming and thermoforming. The factors that increase the inherent difficulty of vacuum forming are similar to those for injection moulding (p.101). An excellent rating indicates that the material is easy to vacuum form. A very poor rating indicates that the material is difficult to vacuum form. Not applicable indicates that the material is either impossible to vacuum form or that it is not commonly commercially practised. The following tables list only those materials which have been assigned a rating of excellent, very good or good for vacuum forming.

Bonding
Post-Processing Bonding This quality is an assessment of the ability of the material to be adhesively bonded by common adhesive systems. Account has been taken of the inherent ease or difficulty of bonding the material. If pre-treatments such as the use of primers, or establishing a particular form of surface e.g. oxidising by corona discharge, are required then that reduces the ratings that have been assigned. However, in the case of polyolefins (polyethylene, polypropylene etc.) which are commonly required to accept an adhesive label, the commercial practises that achieve the required pre-treatment are well established, and thus these materials have been assigned a rating of good, indicating an average ability to be bonded. An excellent rating indicates that the material is easy to bond. A very poor rating indicates that the material is difficult to bond. Not applicable indicates that the material is virtually impossible to bond. The following tables list only those materials which have been assigned a rating of excellent, very good or good for bonding. To further evaluate the processability and performance of any of the listed materials under the desired conditions, refer to the complete comparative data sheets provided on the pages indicated below.

Machining This quality is an assessment of the ability of the material to be machined. Machining includes turning, milling, parting and drilling. Two main factors have been taken into account in assigning rankings: (a) the ability of the material to be easily machined to close tolerances and to a good surface finish, and (b) the level of damage and wear that the material imparts to the cutter. Greater account has been taken of (a) than (b). An excellent rating indicates that the material is easy to machine. A very poor rating indicates that the material is difficult to machine. The following tables list only those materials which have been assigned a rating of excellent, very good or good for machining. To further evaluate the processability and performance of any of the listed materials under the desired conditions, refer to the complete comparative data sheets provided on the pages indicated below.

Welding (Friction) Welding property data and descriptions supplied to The Plastics Compendium - Volume 2 by TWI, Abington Hall, Abington, Cambridge, CB1 6AL, UK. Tel. +44 (0)1223 891162, Fax +44 (0)1223 892588
The Process Friction welding is a technique in which the heat needed to melt the thermoplastic material is generated by pressing one of the parts to be joined against the other and rapidly oscillating it through a displacement. The heat generated by the resulting friction melts the material at the interface in 2-3 seconds. The oscillation is then stopped and the parts are aligned, and held together under pressure until a solid bond is formed. Such bonds are permanent, and have a strength approaching that of the parent material. The main welding parameters associated with friction welding are speed, friction pressure, forge pressure, displacement and duration. These parameters are generally interdependent and for any application a set of weld property optimisation trials would be undertaken prior to mass production of the welded thermoplastic component. Almost any thermoplastic material can be friction welded, including filled, structural foamed, crystalline, and amorphous materials. There is the possibility of welding dissimilar thermoplastics and alloys, and successful joints can be made with, for instance, PS and ABS, PMMA and PC, PPO/PA and PA, and PP and HDPE. Friction welding encompasses spin and orbital welding and vibration welding. An excellent rating indicates that the material is easy to friction weld. A very poor rating indicates that the material is difficult to friction weld. Not applicable indicates that the material is impossible to friction weld.
Welding (Friction - Spin/Orbital) Spin Welding The principle behind spin welding is similar to that of vibration welding. The joint areas are always circular and the motion is direct rotational. Direct rotational friction welding (spin welding) of thermoplastics can involve relatively simple pieces of equipment such as lathes or drilling machines. A lathe would produce a constant speed during the frictional heating stage (continuous drive friction welding) and a drilling machine would produce a reducing speed characteristic during the frictional heating stage (inertia friction welding). In practice, purpose built machines are generally employed for spin welding to provide greater control and they may be of either the continuous drive or inertia type. Spin welding has been exploited for applications as diverse as the manufacture of polyethylene floats, aerosol bottles, transmission shafts and PVC pipes and fittings. Apart from being a fast technique, another particular advantage is that welds can be formed beneath the surface of a liquid.
Orbital Friction Welding Orbital welding is another frictional technique for joining thermoplastic parts, where each point on the surface orbits a different point on the face of the stationary part. The orbit is of constant rotational speed and is identical for all points on the joint surface. This motion is stopped after sufficient material is melted and the thermoplastic then solidifies to form a weld. Orbital welding is a relatively new technique, and the first welding units are being marketed as devices to fill the size gap between benchtop ultrasonic units and linear vibration welders. This means that items such as medium sized automotive components (fluid reservoirs etc.) may be joined using this process. The following tables list only those materials which have been assigned a rating of excellent, very good or good for spin/orbital friction welding. To further evaluate the processability and performance of any of the listed materials under the desired conditions, refer to the complete comparative data sheets provided on the pages indicated below.

Welding (Friction - Vibration) Linear Vibration Welding The principle behind linear vibration welding is that the parts to be joined are brought into contact, under pressure, before being moved so that the joint areas rub together with a linear reciprocating motion. The parts are vibrated through a relatively small displacement. The displacement, commonly referred to as the amplitude, is typically between 0.07 and 1.8mm, with a frequency of vibration of 200Hz (high frequency), or 2-4mm at 100Hz (low frequency), in the plane of the joint. Industrial applications tend to be based around linear joints which are sufficiently long so that ultrasonic welding cannot be easily accomplished (approximately 200mm) and hot plate welding would typically take many minutes to perform.
Typical Applications Automotive: Two-part bumper, fuel tanks, fuel pumps, expansion vessels, instrument panels, air channels, parcel shelves, inner door panels, hermetic sealing of a length of air ducting to the internal surface of a dash-board. Consumer: Spectacle frames, typewriter covers. Industrial:
Filter housings, motor saw housings, heating valves, air ducting.
Angular Vibration Welding The principle behind angular vibration welding is similar to linear vibration except that the motion is angular. In spin welding it is not possible to determine where one half of the component will end up in relation to the other half when welded. In angular welding the components are preassembled and vibrated in an angular motion through a few degrees. When the weld cycle is complete the component parts are returned to the pre-welded position ensuring good alignment. The angular friction welding process is used for circular components where upper and lower component alignment is critical. This quality indicates the ability of the material to form a weld with itself by vibration welding. Welding of dissimilar materials is not covered. The following tables list only those materials which have been assigned a rating of excellent, very good or good for linear or angular vibration welding. To further evaluate the processability and performance of any of the listed materials under the desired conditions, refer to the complete comparative data sheets provided on the pages indicated below.

The Process Hot gas welding of thermoplastics is a manual welding process. A stream of hot gas, typically air, but it can be nitrogen, is directed towards the joint between the two thermoplastic parts to be joined, where it softens or melts the polymer. A filler rod is also heated in the stream of hot gas and this is fed between the two parts. A weld is formed by the fusing together of the thermoplastic parts and the filler rod. The hot gas welding tool consists of a heater unit to heat the gas and a nozzle to direct the gas onto the workpieces. If air is used, this is provided by either a remote air compressor or an integral blower. If nitrogen is used, suitable connection to a gas supply is made. The temperature of the hot gas stream is governed via the electrical supply to the heater and is typically in the range 200400°C. A range of nozzle shapes is available and selection is based on the type of weld preparation. Thermoplastic consumable filler rods are generally circular in section although rods with triangular section are also available in most thermoplastic materials. It is important that the same base material is used for both the filler rod and two parts to be joined. Hot gas welding is a manual process which is applicable to most thermoplastics and its success depends greatly on the skill of the operator. The adjustable welding parameters are gas type, flow rate and temperature, and the angle of the filler rod to the parts being welded (90° approximately). Typical gas flow rates are in the range 16-60 litre/minute. The main advantage of hot gas welding is that the equipment is easily portable. The main disadvantages of the process are that it is slow and weld quality is operator dependent.
Types of Welding There are three main types of hot gas welding: (a) Hand Welding or Pendulum Welding: Where the welded joint is to be short, around a small radius or difficult to access. The welding gun is moved in pendulum fashion along the joint axis heating both the rod and joint groove. (b) Speed Welding: Where the welded joint is to be a long run, a gentle radius and easy to access. The welding rod is fed through a speed welding nozzle into a prepared groove. The nozzle outlet is designed to give the correct relationship of hot gas onto the rod and weld area. (c) Extrusion Welding: NB - This process is not covered in this volume and is therefore presented here for information purposes only. Where the welded joint is a thick section extrusion welding is similar to hot gas welding, except that the filler material is separately heated in the barrel of a hand-held screw extruder. The molten material is then extruded through a PTFE die into the joint. The joint is pre-heated using a hot gas nozzle mounted on the extruder barrel.

Welding (Hot Plate)
Welding (Hot plate) Welding property data and descriptions supplied to The Plastics Compendium - Volume 2 by TWI, Abington Hall, Abington, Cambridge, CB1 6AL, UK. Tel. +44 (0)1223 891162, Fax +44 (0)1223 892588
The Process Hot plate welding is probably the simplest yet most versatile plastic joining technique. Its uses vary from welding small components to large pipelines. The technique involves: i)
Pressing the parts to be joined against either side of a heated platen.
ii)
Removing the platen when the parts are sufficiently molten.
iii) Pressing the components together and holding them until they are cooled. The heated plates are usually flat, but more complex shapes can be used to weld a three-dimensional joint profile. Welding equipment may be readily portable for on-site use or fixed for factory use. In either case the heat is usually applied electrically by resistance heaters or sometimes by the use of hot gas or gas burners. The surface of the hot plate is usually coated with PTFE to prevent the adherence of molten plastic. The main welding parameters are the temperature of the hot plate, the heating time, the welding pressure and the welding time. Most thermoplastic materials can be joined using hot plate welding. Problems encountered when welding nylon are attributed to surface oxidation leading to poor joint integrity. If the correct procedures are followed welds with joint tensile strengths equal to the parent material strength can be obtained. Hot plate welding is a relatively slow process with weld times ranging from 10 seconds for small components up to 60 minutes for parts with a large joint area. Hot plate welding is usually fully automatic and used for welding mass-produced injection moulded parts.
Types of Welding There are three other types of heated tool welding, and these are particularly used for joining pipework: (a) Socket: A shaped heated tool is used to heat the outside of the pipe and the inside of the socket. (b) Butt Fusion: Perhaps the single most important application is in the welding of thermoplastic pipes for gas distribution, water distribution, effluent and sea outfalls. (c) Saddle: A shaped heated tool is used to heat the top outside surface of the pipe and the under-side of the saddle fitting.
Typical Applications Automotive: Hydraulic fluid reservoirs and battery cases. Building:
Welding of unplasticised PVC door and window frames.
Pipework:
Welding of thermoplastic pipes for gas, water, effluent and sea outfall distribution.

Welding (Radio Frequency) Welding property data and descriptions supplied to The Plastics Compendium - Volume 2 by TWI, Abington Hall, Abington, Cambridge, CB1 6AL, UK. Tel. +44 (0)1223 891162, Fax +44 (0)1223 892588
The Process Radio frequency (RF) welding, sometimes known as dielectric welding or high frequency (HF) welding, is the process of fusing materials together by applying radio frequency energy to the area to be joined. The resulting weld can be as strong as the original workpiece materials. RF welding relies on certain properties of the material in the parts being welded to cause the generation of heat in a rapidly alternating electric field. This means that only certain materials can be dielectrically welded. The process revolves around subjecting the parts to be joined to a high frequency electric field which is normally applied between two metal bars. These bars also act as pressure applicators during heating and cooling. The dynamic electric field causes the molecules in some thermoplastics to oscillate. Depending on their geometry and dipole moment, these molecules may translate some of this oscillatory motion into thermal energy and cause heating of the material. A measure of this interaction is the loss factor ε'' which is temperature and frequency dependent. The most widely used material in RF welding is polyvinyl chloride (PVC). Other thermoplastics that can be welded are EVA and polyurethanes. Nylon sheeting, although difficult to tear seal, can be welded if preheated electrodes are used. Thermoplastics which cannot be welded by this process include polyethylene, polypropylene and PTFE.
Types of Welding There are two main types of RF welding: (a) Plain Welding: The welding of two or more thicknesses of material, the welding tool can be engraved or profiled to give the welded area a decorative appearance. The welding process can incorporate ‘blind’ embossing which places lettering, logos or decorative effects on the welded items. (b) Tear-Seal Welding: The dual process of simultaneously welding and cutting (cut and seal) a material. This is achieved by incorporating a cutting edge adjacent to the welding edge. This compresses the hot plastic enough to allow the excess scrap material to be torn off. Another technique used is applique welding, where a piece of material is cut out and welded to the surface of another to provide an ornamental effect.
Typical Applications A wide range of products can be manufactured using the RF welding technique. The range of products is increasing as new applications are found. A few examples are listed below: Automotive:
Air bags and dashboard fascia.
Household Items:
Headboards, chair upholstery, quilting and table mats.
Inflatable Items:
Beach balls, toys, air/water beds, rafts and life jackets.
Large Items:
Tarpaulins, tents, marquees, pool liners and lorry covers.
Medical Items:
Blood bags and colostomy bags.
Stationery:
Book covers, stationery wallets, zip bags, binders and office files.

Welding (Ultrasonic) Welding property data and descriptions supplied to The Plastics Compendium - Volume 2 by TWI, Abington Hall, Abington, Cambridge, CB1 6AL, UK. Tel. +44 (0)1223 891162, Fax +44 (0)1223 892588
The Process Ultrasonic welding involves the use of high frequency sound energy to soften or melt the thermoplastic at the joint. Parts to be joined are held together under pressure and are then subjected to ultrasonic vibrations usually at a frequency of 20 or 40kHz. The ability to weld a component successfully is governed by the design of the equipment, the mechanical properties of the material to be welded and the design of the components. Since ultrasonic welding is very fast (weld times are typically less than 1 second) and easily automated, it is a widely used technique. In order to guarantee the successful welding of any parts, careful design of components and fixtures is required and for this reason the technique is best suited for mass production. An ultrasonic welding machine consists of four main components: a power supply, a converter, an amplitude modifying device (commonly called a booster) and an acoustic tool known as the horn (or sonotrode). The power supply changes mains electricity at a frequency of 50-60Hz, into high frequency electrical supply operating at 20-40kHz. This electrical energy is supplied to the converter. Within the converter, discs of piezoelectric material are sandwiched between two metal sections. These discs are clamped tightly together, and are always held in compression. The converter changes the electrical energy into mechanical vibratory energy at ultrasonic frequencies. Most ultrasonic welding machines operate at 20kHz. This is above the highest frequency generally detected by the human ear. The vibratory energy is then transmitted through the booster. The booster increases the amplitude of the sound wave. The sound waves are then transmitted to the horn. The horn is an acoustic tool that transfers the vibratory energy directly to the parts being assembled, and it also applies a welding pressure. The vibrations are transmitted through the workpiece to the joint area. Here the vibratory energy is converted to heat through friction - this then softens or melts the thermoplastic, and joins the parts together. Benefits of the process include: energy efficiency, high productivity with low costs, ease of automated assembly line production and fast joining times. The main limitation to the process is that the maximum component length which can be welded by a single horn is approximately 250 mm. This is due to limitations in the power output capability of a single transducer, the inability of the horns to transmit very high power, and amplitude control difficulties due to the fact that joints of this length are comparable to the wavelength of the ultrasound in the horn.

The Plastics Compendium - Volume 2, Comparative Materials Selection Data Types of Welding Welding: The process of generating melt at the mating surfaces of two thermoplastic parts. When ultrasonic vibrations stop, the molten material solidifies and a weld is achieved. The resultant joint strength approaches that of the parent material; with proper part and joint design, hermetic seals are possible. Ultrasonic welding allows fast, clean assembly without the use of consumables. Ultrasonic vibratory energy is also used in several distinct assembly and finishing techniques. The following processes are not covered by the ranking system and are therefore presented here for information purposes only. (a) Staking: The process of melting and reforming a thermoplastic stud to mechanically lock a dissimilar material in place. Short cycle times, tight assemblies, good appearance of final assembly, and elimination of consumables are possible with this technique. Polypropylene is difficult to weld but easy to stake. (b)
Inserting: Embedding a metal component (such as a threaded insert) in a preformed hole in a thermoplastic part. High strength, reduced moulding cycles and rapid installation with no stress build-up are some of the advantages.
(c) Swaging/Forming: Mechanically capturing another component of an assembly by ultrasonically melting and reforming a ridge of plastic or reforming plastic tubing or other extruded parts. Advantages of this method include speed of processing, less stress build-up, good appearance, and the ability to overcome material memory. (d) Spot Welding: Ultrasonic spot welding is an assembly technique for joining two thermoplastic components at localised points without the necessity for preformed holes or an energy director. Spot welding produces a strong structural weld and is particularly suitable for large parts, sheets of extruded or cast thermoplastic, and parts with complicated geometry and hard-to-reach joining surfaces. (e) Slitting: The use of ultrasonic energy to slit and edge-seal knitted, woven and non-woven thermoplastic materials. Smooth, sealed edges which will not unravel are possible with this method. There is no “bead” or build-up of thickness on the slit edge to add bulk to rolled materials. (f)
Textile/Film Sealing: Fabric and film sealing utilises ultrasonic energy to join thin thermoplastic materials. Clear, pressuretight seals in films, and neat, localised welds in textiles may be accomplished. Simultaneous cutting and sealing is also possible. A variety of patterned anvils are available to provide decorative and functional “stitch” patterns.
Typical Applications Ultrasonic assembly is the method of choice for many applications in the automotive, appliance, medical, textile, packaging, toy and electronics markets, among others. The basic advantages of ultrasonic assembly - fast, strong, clean and reliable welds are common to all markets. However, each market has specialised needs that they rely on ultrasonic assembly to meet. Appliances: In this high-volume market, hermetic sealing and also cosmetic appearance are important. Applications include: steam irons, pump housings, vacuum cleaner wands, and dishwasher spray arms. Automotive: Hermetic seals in applications such as lenses, filters and valves. Other applications include: glove box doors, instrument clusters, air diverters and mass airflow sensors. Business:
“Clean” assemblies with reduce particulate matter are produced on information storage discs. Other applications include the assembly for ribbon cartridges, and audio and video cassettes.
Consumer:
Precision welding, staking and forming operations make the Swatch watch possible.
Electrical:
Multiple staking and inserting applications are often automated for high-volume production requirements with consistent reliability. Applications include: terminal blocks, connectors, switches (e.g. toggle, dip, rotary quick and diaphragm), and bobbin assemblies.
Medical:
Non-contamination and the ability to be operated in a clean room are as important as the strength of the weld. Reliable, repeatable assemblies for critical life-support devices are produced with new capabilities in process control. Applications include: arterial filters, cardiometry reservoirs, blood/gas filters, face masks and IV spike/ filters.
Packaging: From the aseptic packages to toothpaste tubes, the ability of ultrasonic assembly to seal through product contamination in the joint area is a major advantage. In addition to good cosmetic appearance, ultrasonic assembly provides tamper-evident seals for blister packs. Applications include: condiment dispensers, lock blister packages, juice pouches, juice cartons and plastic coated paper cups. Toys:

In this highly competitive industry, the elimination of adhesives, screws and solvents, or other consumables is a bonus added to strong, safe, flash-free assemblies.
