General Description : Made in both homopolymer and copolymer forms which do not differ greatly. Both are hard, tough, stiff polymers with excellent abrasion resistance and good appearance (can give high surface gloss). Normally highly crystalline and opaque, their natural colour is white but they are often used coloured. They have poor resistance to U.V. and generally to acids and alkalis. The homopolymer has slightly better mechanical properties but somewhat worse thermo-oxidative stability than the copolymer. Only the copolymer is suitable for continuous use with hot water.

Applications are wide-ranging including gears, bearings, snap fittings and many other engineering components, plumbing fittings, appliance casings and jug kettles.
