great rigidity impact resisitant EPT POM EPT derlin EPT
POM (Full-identify: EPTformaldehyde), is a EPTs of non-side-EPT, EPT, substantial crystalline and linear polymer, which is praised quotPlastic Metal quot, and has complete outstanding performances, such as: wear-resistance, substantial hardness, anti-impregnant, great rigidity (Tensile modulus of elasticity), chemical steadiness, isolation resistance and dimensional balance. POM has commonly used in EPTT EPTT, electronic and electrical products, commodity, pipeline amp fittings, exact apparatus and so on, which can be instead of the bronze, Zinc, tin and other metals.
Except POM-H, is usually copolymerized with ethylene oXiHu (West EPT) Dis.de collectively, in orEPTTto keep away from the melting of POM materials in the large temperature. POM-H has the EPT performances than POM-C in its high crystalline, mechanical strength and rigidity. And POM-C has the EPT performances than POM-H in its minimal melting point, temperature balance, fXiHu (West EPT) Dis.Hu (West EPT) Dis.on attribute and machining ability.
Father far more, POM-H PTFE, which is created from the Delrin POM Resin that maxed Teflon fiber symmetrically, has the lower co-effective of frication, very good lubrication, dress in-resistance, non-creepage resistance.
