wear-resistance plastic EPT Delrin EPT pom EPT
Description:
POM (Entire-name: EPTformaldehyde), is a EPTs of non-facet-EPT, EPT, large crystalline and linear polymer, which is praised quotPlastic Metal quot, and has extensive excellent performances, such as: dress in-resistance, high hardness, anti-impregnant, great rigidity (Tensile modulus of elasticity), chemical security, isolation resistance and dimensional balance. POM has widely utilized in EPTT EPTT, digital and electric products, commodity, pipeline amp fittings, exact apparatus and so on, which can be as an alternative of the bronze, Zinc, tin and other metals.
Other than POM-H, is typically copolymerized with ethylene oXiHu (West EPT) Dis.de with each other, in orEPTTto keep away from the melting of POM material in the higher temperature. POM-H has the EPT performances than POM-C in its large crystalline, mechanical strength and rigidity. And POM-C has the EPT performances than POM-H in its lower melting position, temperature steadiness, fXiHu (West EPT) Dis.Hu (West EPT) Dis.on attribute and machining ability.
Father a lot more, POM-H PTFE, which is created from the Delrin POM Resin that maxed Teflon fiber symmetrically, has the low co-efficient of frication, very good lubrication, use-resistance, non-creepage resistance.
