1.engineering plastic of non-side-chain

2.high density

3.linear polymer

ACETAL ROD    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.       Acetal Rod   Mechanical  Properties
