POM&lparPolyformaldehyde&rpar is a engineering plastics of non-aspect-chain&comma higher density&comma large crystalline and linear polymer&comma which is praised “CZPT Steel”&comma and has thorough excellent performances&comma this kind of as&colon Dress in-resistance&comma substantial hardness&comma anti-impregnant&comma very good rigidity &lparTensile modulus of elasticity&rpar&comma chemical security&comma isolation resistance and dimensional security&time period POM has widely applied in Vehicle industries&comma electronic and electric powered merchandise&comma commodity&comma pipeline & fittings&comma precise equipment and so on&comma which can be rather of the bronze&comma Zinc&comma tin and other metals&period of time
Except POM-H is frequently copolymerized with ethylene oxide with each other&comma in purchase to stay away from the melting of POM content in the high temperature&time period POM-H has the much better performances than POM-C in its high crystalline&comma mechanical strength and rigidity&time period And POM-C has the much better performances than POM-H in its lower melting level&comma temperature security&comma fluxion characteristic and machining capacity&period
Father far more&comma POM-H&plusPTFE&comma which is manufactured from the Delrin POM Resin that maxed Teflon fiber symmetrically&comma has the low co-successful of frication&comma very good lubrication&comma use-resistance&comma non-creepage resistance&period of time
Auto industries&colon POM has a big application in car industries&comma due to the fact the mechanical areas produced by POM&comma which has the benefits of higher mechanical toughness&comma high hardness&comma very good wear-resistance&comma reduced co-efficient of friction&comma effortless to sustain&comma reducing value and so on&comma can be used in vehicles alternatively of coppery half stalk and planet gear&period of time It not only conserving copper components&comma but also improving support existence&period At the engine gas method&comma components for hose valves and circumstance protect of radiator&comma cooling fluid’s standby case&comma h2o valve&comma oil box’ protect&comma pump impeller&comma shell of gasification device and accelerator pedal and so on&period
Electronic and electric CZPT&colon Because of its decrease electricity consuming&comma high dielectric energy and insulation resistance and digital arc resistance&comma POM has extensively utilized in electronic and electrical CZPT&comma these kinds of as&colon Shell of electronic spanner&comma shell of electronic scissors&comma shell of coal drilling machine&comma handle of switch&comma areas also for cellphone&comma wi-fi recorder&comma video clip tape recorder&comma tv&comma computer&comma electrograph&comma calculagraph&comma bracket of recorder tape and so on&interval
