good rigidity influence resisitant EPT POM EPT derlin EPT
POM (Complete-title: EPTformaldehyde), is a EPTs of non-side-EPT, EPT, higher crystalline and linear polymer, which is praised quotPlastic Steel quot, and has thorough exceptional performances, these kinds of as: dress in-resistance, higher hardness, anti-impregnant, good 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, actual equipment and so on, which can be as an alternative of the bronze, Zinc, tin and other metals.
Except 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 high temperature. POM-H has the EPT performances than POM-C in its substantial crystalline, mechanical power and rigidity. And POM-C has the EPT performances than POM-H in its reduced melting stage, temperature security, fXiHu (West EPT) Dis.Hu (West EPT) Dis.on attribute and machining capability.
Father more, POM-H PTFE, which is made from the Delrin POM Resin that maxed Teflon fiber symmetrically, has the lower co-successful of frication, great lubrication, put on-resistance, non-creepage resistance.
