Engineering Plastics & Their Properties

24 March 2021

At FWB, we stock a wide range of engineering plastics suitable for a wide range of domestic and industrial applications. The properties of each of these plastics differ, making certain plastics more suitable for particular applications. Here's a breakdown of some of the most frequently used engineering plastics and their properties:

Nylon 6

A general engineering plastic with excellent versatility that is both strong and hard wearing. Nylon 6 is typically used for pulleys, bearings, rollers, gears and more.

Nylon 6-6

Nylon 6-6 is a stiffer plastic than Nylon 6, with better absorption and chemical resistance.


Acetol-C is a high strength plastic with a low coefficient of friction and good dimensional stability. Acetol C features lower moisture absorption than Nylon materials, making it more suitable for marine applications, as well as electrical insulation parts.


PVC is an excellently chemical resistant material, ideal for pump components, acid/chemical tank parts, templates and jigs.


Polypropylene features excellent chemical resistance and impact strength and can be welded and fabricated. It is commonly used as cladding in the food industry.


Polycarbonate offers a very high transparency and excellent impact resistance, making it a very popular material for industrial glazing and guarding applications.


PTFE, commonly referred to as Teflon, is used in a huge number of domestic and industrial applications. The advantages of PTFE are that it has a low coefficient of friction, high flex strength, high temperature resistance and its resistance to both water and chemicals.


Also referred to as Perspex or Plexiglass, acrylic is a transparent plastic material with excellent strength, good stiffness, and excellent clarity. Acrylic is often used as an alternative to glass where safety and security are a concern, as it offers the same clarity as glass but does not shatter when it breaks and is much lighter. Acrylic is easy to fabricate, can be bonded with adhesives and solvents and is available in a variety of colours.


PEEK, or Polyether Ether Ketone, has the highest heat resistance in thermal plastics and can operate at 240°C continuously or 300°C short term. This thermal plastic self-lubricates and excels in impact, fatigue, radiation and chemical resistance. PEEK is flame resistant and an excellent electrical insulator.
