Features Ultra High Molecular Weight Polyethylene (UHMW-PE) has the highest impact and abrasion resistance of any thermoplastic. These properties, along with its extremely low coefficient of friction, make UHMW ideal for wearing surfaces such as flight wear shoes and floor rails. Additionally, UHMW's high tensile strength and lack of water absorption make it the best material for sprockets and other applications where durability and dimensional stability are crucial. UHMW also offers excellent chemical resistance for harsh applications. Nylons Nylon is available in several compounds and copolymers. The most commonly used nylons for industrial components are TYPE 6 (Cast) and TYPE 6/6 (Extruded). Both materials exhibit excellent wear resistance and tensile strength with type 6 offering slightly better mechanical properties. Nylon generally absorbs more moisture than other bearing materials and therefore may be dimensionally unstable in wet applications requiring close tolerances. Nylon is available in oil or molybdenum disulphide filled compounds which offer a lower coefficient of friction for bearings and wear parts. Phenolics This group of high pressure laminated materials consists of two components, a thermosetting resin and a reinforcing material such as paper, linen, or canvas. As one of the oldest forms of plastic, industrial laminants are widely used as printed circuit boards, power insulators, gears and pulleys. All phenolic grades exhibit good dielectric strength, dimensional stability, and chemical resistance. PTFE Polytetrafluoroethylene (PTFE) provides exceptional chemical, electrical, mechanical and thermal properties for many applications. The most recognized source of PTFE resin is teflon manufactured by DuPont. PTFE is capable of operating at temperatures up to 550°F making it a versatile high temperature material. Glass fibers are often added to improve the dimensional stability of PTFE under load.
