We have manufactured all types of extruded tubes and profiles in a wide variety of material specifications and we stock many standard grades of material, which have been used successfully by many diverse industries. However, we would strongly advise involving Naylor Specialist Plastics at the design stage, as we may be able to help with additional information and advise on the suitability of a particular grade. Although plastics in general have many advantages over traditional alternatives the following information should only be used as a guide, and does not represent a guaranteed solution for your particular application.

Materials	Full Name	Properties	Temperature Range
LDPE	Low Density Polyethylene	Has outstanding flexibility at very low temperatures, with very good chemical resistance.  Potable water grades are available.	-40 to +60 Degrees Celsius
MDPE	Medium Density Polyethylene	Manufactured from PE80. Suitable for fusion or compression fittings. Resistant to agressive chemicals with a high abrasion resistance.	-40 to +60 Degrees Celsius
HDPE	High Density Polyethylene	Is widely used for buried gas and water pipelines.   It has very low friction loss with excellent abrasion and chemical resistance.	-40 to +60 Degrees Celsius
PP	Polypropylene	Has excellent resistance to most chemicals and high heat (as high as 110 Degree Celsius for certain grades) good abrasion resistance.  Please note: Generally unsuitable for outdoor use unless stabilised against the effect of UV light (Ultra Violet).	-10 to +110 Degrees Celsius
ABS	Acrylonitrile Butadiene Styrene	Has exceptional impact strength, it is also non-toxic and is suitable for use at low temperatures (as low as -40 Degree Celsius).   It is light weight, easy to join with solvent cement and has good chemical resistance, this makes ABS an excellent choice for most types of pipe-work.	-40 to +70 Degrees Celsius
PVC	Polyvinyl Chloride	Is probably the oldest and most commonly used plastic today.  In rigid form it has a working temperature of between 60 Degree Celsius and can be easily joined with solvent cement.  Flexible grades are used for a wide range of low pressure tube applications with food quality grades available.	0 to +60 Degrees Celsius
HIPS	High Impact Polystyrene	Is tough, rigid and is available in crystal clear grades that make it the ideal material for packaging and point of sale applications.  It has a maximum service temperature of 75Degree Celsius with only limited resistance to dilute acids or alkalis.  Not generally suitable for outdoor use.	75 Degrees Celsius
F-PVC	Flexible - Polyvinyl Chloride	Inherently Flame Retardant with excellent electrical properties	0 to +60 Degrees Celsius
EVA	Ethylene Vinyl Acetate	Extremly flexible and transparent in it's natural state. Excellent resistance to Hydro Carbon's also with good chemical resitance	-70 to +60 Degrees Celsius
TF-PP	Talc Filled - Polypropylene	Increases rigidity to standard Polypropylene	-10 to +110 Degrees Celsius

Friction Resistance
Our preferred suppliers of raw materials have complied a "league table" of polymer resistance to abrasion and friction as shown in the table below.

This table gives general characteristics for generic types of plastic. However, we would strongly advise comprehensive testing of the finished product wherever possible, as abrasion resistance can be affected by many factors in the working environment such as temperature or the presence of lubricants or chemicals.

1. PP-HP Polypropylene Homo Polymer very good friction properties and good abrasion resistance. The greater range of working temperature (up to 100° C) can be an advantage
2. PP-CP Polypropylene Co- Polymer slightly less friction resistance than Homo polymer but good all round mechanical strength. Excellent temperature resistance
3. HDPE High Density Polyethylene
4. MDPE Medium Density Polyethylene. Or LLDPE (linear low density)
5. LDPE low density polyethylene poor friction and wear characteristics
6. PVC Polyvinyl Chloride. In rigid form it has a working temperature of 0 to 60° C with only moderate abrasion resistance
7. ABS Acrylonitrile butadiene styrene has a poor friction co-efficient and only average abrasion resistance
8. HIPS High Impact Styrene very poor friction and abrasion resistance
