Description:

POM (Full-name: Polyformaldehyde), is a engineering plastics of non-side-chain, high density, high crystalline and linear polymer, which is praised "Plastic Steel", and has comprehensive excellent performances, such as: wear-resistance, high hardness, anti-impregnant, good rigidity (Tensile modulus of elasticity), chemical stability, isolation resistance and dimensional stability. POM has widely applied in Automobile industries, electronic and electric products, commodity, pipeline & fittings, exact apparatus and so on, which can be instead of the bronze, Zinc, tin and other metals.
 
Except POM-H, is often copolymerized with ethylene oxide together, in order to avoid 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 better performances than POM-H in its low melting point, temperature stability, fluxion characteristic and machining capability.
Father more, POM-H+PTFE, which is made from the Delrin POM Resin that maxed Teflon fiber symmetrically, has the low co-efficient of frication, good lubrication, wear-resistance, non-creepage resistance.
