Skilled make injection moulding POM gears
Description:
POM (Entire-title: CZPT formaldehyde), is a CZPT plastics of CZPT -aspect-chain, high density, high crystalline and linear polymer, which is praised “Plastic Steel”, and has thorough exceptional performances, such as: dress in-resistance, high hardness, anti-impregnant, great rigidity (Tensile modulus of elasticity), chemical stability, isolation resistance and dimensional stability.
POM has broadly applied in CZPT cellular industries, electronic and electrical items, commodity, pipeline & fittings, precise equipment and so on, which can be as an alternative of the bronze, Zinc, tin and other metals.
Besides POM-H, is typically copolymerized with ethylene oxide together, in purchase to steer clear of the melting of POM substance in the substantial temperature. POM-H has the far better performances than POM-C in its large crystalline, mechanical toughness and rigidity.
And POM-C has the far better performances than POM-H in its lower melting stage, temperature stability, fluxion attribute and machining ability.
Father much more, POM-H+PTFE, which is made from the Delrin POM Resin that maxed Teflon fiber symmetrically, has the minimal co-efficient of frication, very good lubrication, wear-resistance, CZPT -creepage resistance.
