POM EPT little-module precision cylindrical spur EPT
Description:
POM (Full-identify: EPTformaldehyde), is a EPTs of non-facet-EPT, EPT, large crystalline and linear polymer, which is praised quotPlastic Metal quot, and has thorough exceptional performances, such as: put on-resistance, higher hardness, anti-impregnant, good rigidity (Tensile modulus of elasticity), chemical steadiness, isolation resistance and dimensional stability. POM has broadly utilized in EPTT EPTT, digital and electric merchandise, commodity, pipeline amp fittings, specific equipment and so on, which can be alternatively of the bronze, Zinc, tin and other metals.
Apart from POM-H, is usually copolymerized with ethylene oXiHu (West EPT) Dis.de jointly, in orEPTTto keep away from the melting of POM materials in the substantial temperature. POM-H has the EPT performances than POM-C in its high crystalline, mechanical toughness and rigidity. And POM-C has the EPT performances than POM-H in its reduced melting level, temperature security, fXiHu (West EPT) Dis.Hu (West EPT) Dis.on attribute and machining capability.
Father far more, POM-H PTFE, which is manufactured from the Delrin POM Resin that maxed Teflon fiber symmetrically, has the lower co-effective of frication, great lubrication, use-resistance, non-creepage resistance.
