POM (Polyoxymethylene, Acetal) is a high-crystallinity engineering thermoplastic with excellent mechanical stiffness, low friction, high dimensional stability and good fatigue resistance.
Description
POM (homopolymer or copolymer) has an exceptionally high degree of crystallinity, resulting in high stiffness, low friction coefficient and excellent dimensional stability over a wide temperature range. Natural POM is white; it is easily machined and injection-moulded.
Applications
POM is used in precision gears, bearings, fuel system components, zippers, automotive sensors and consumer electronics.
