Scientific name of POM POM: polyformaldehyde, polyethylene oxide polyoxymethylene (POM), also known as steel, special steel. It is at the raw material such as formaldehyde aggregate income. POM -h (polyoxymethylene homopolymer), POM (polyoxymethylene copolymer) - K is high density, high degree of crystallinity of thermoplastic engineering plastic. Have good physical, mechanical and chemical properties, especially have excellent friction resistance.
features
1, POM has very low friction coefficient and good geometric stability, especially suitable for the production of gear and bearing
2, POM with high temperature resistant properties, therefore is also used in pipeline device (pipe valves, pump shell), lawn equipment.
4, the high degree of crystallization of POM caused it to have a fairly high shrinkage rate, can achieve 2% ~ 3.5% higher. For a variety of enhanced materials have different shrinkage rate.
5, POM is a crystalline plastics, melting point, once reached melting point, the melt viscosity drops rapidly.
