Description:

POM (Full-identify: Polyformaldehyde), is a engineering plastics of non-side-chain, high density, large crystalline and linear polymer, which is praised “CZPT Steel”, and has complete superb performances, such as: use-resistance, large hardness, anti-impregnant, excellent rigidity (Tensile modulus of elasticity), chemical security, isolation resistance and dimensional security. POM has broadly applied in Vehicle industries, electronic and electric goods, commodity, pipeline & fittings, actual apparatus and so on, which can be rather of the bronze, Zinc, tin and other metals.
 
Besides POM-H, is typically copolymerized with ethylene oxide jointly, in get to keep away from the melting of POM material in the high temperature. POM-H has the better performances than POM-C in its high crystalline, mechanical strength and rigidity. And POM-C has the much better performances than POM-H in its low melting position, temperature security, fluxion characteristic and machining capability.
Father far more, POM-H+PTFE, which is manufactured from the Delrin POM Resin that maxed Teflon fiber symmetrically, has the low co-successful of frication, good lubrication, put on-resistance, non-creepage resistance.
