Its wear resistance and self-lubricating material than most engineering materials offer superior pom, good oil resistance, peroxide performance, no acid and intolerance ultraviolet radiation, POM good electrical insulation, almost independent of temperature and humidity. Divided POM POM (POM-H) and acetal copolymer (POM-K). POM density, crystallinity, melting point are high pom manufacturers of raw materials, but poor thermal stability, narrow processing temperature (10 degrees), slightly worse on the pH stability; acetal copolymer density, crystallinity, low melting point, but hot good stability, easy to break down, the processing temperature (50 degrees). POM characteristics and uses: (1) low coefficient of friction and good geometric stability, particularly suitable for the production of gears and bearings; (2) good high temperature performance for pipe fittings (pipe valve, pump housing), lawn equipment; (3) tough, flexible, low-temperature creep resistance; (4) having a high crystallinity resulting in a relatively high shrinkage (1.2-3.0%); (5) melting point significantly, once they reach the melting point, melt viscosity decline rapidly. pom raw materials plant, Shijie pom raw materials, plastic Jichang provided by Dongguan Chang Ping Jichang plastic materials.
