engineering plastic delrin sheet acetal board polyacetal cnc machining parts pom plastic sheet
POM (Complete-identify: Polyformaldehyde), is a engineering plastics of non-side-chain, substantial density, higher crystalline and linear polymer, which is praised “CZPT Steel”, and has comprehensive exceptional performances, such as: wear-resistance, higher hardness, anti-impregnant, great rigidity (Tensile modulus of elasticity), chemical balance, isolation resistance and dimensional security. POM has broadly applied in Automobile industries, electronic and electric merchandise, commodity, pipeline & fittings, exact apparatus and so on, which can be rather of the bronze, Zinc, tin and other metals.
Apart from POM-H, is frequently copolymerized with ethylene oxide together, in purchase to keep away from the melting of POM materials in the high temperature. POM-H has the far better performances than POM-C in its large crystalline, mechanical energy and rigidity. And POM-C has the much better performances than POM-H in its minimal melting position, temperature stability, fluxion characteristic and machining capacity.
Father more, POM-H+PTFE, which is manufactured from the Delrin POM Resin that maxed Teflon fiber symmetrically, has the minimal co-productive of frication, excellent lubrication, dress in-resistance, non-creepage resistance.
Vehicle industries: POM has a large software in car industries, simply because the mechanical components created by POM, which has the advantages of higher mechanical power, large hardness, great dress in-resistance, lower co-effective of friction, simple to preserve, decreasing cost and so on, can be used in cars instead of coppery 50 percent stalk and world equipment. It not only conserving copper components, but also strengthening support lifestyle. At the motor gas program, factors for hose valves and circumstance go over of radiator, cooling fluid’s standby circumstance, h2o valve, oil box’ protect, pump impeller, shell of gasification equipment and accelerator pedal and so on.
Electronic and electrical CZPT: since of its lower electrical power consuming, high dielectric energy and insulation resistance and digital arc resistance, POM has broadly used in digital and electrical CZPT, this sort of as: shell of electronic spanner, shell of electronic scissors, shell of coal drilling machine ,take care of of swap, components also for telephone, wi-fi recorder, video clip tape recorder, tv, personal computer, electrograph, calculagraph, bracket of recorder tape and so on.
Agricultural equipment: element of manual sprayer, joint and transport element of seeder, areas of milk device, shell of irrigation and drainage, valve, joint and bush of drinking water and so on.
Pharmacy & packing Machine: transporting screw, earth equipment, equipment bar, chain wheel and cushion bar and so on.
CZPT industries: drinking water faucet, window body, wash pot, water tank, pulley for portiere, shell of h2o meter and tie-in of drinking water pipe.
Shade:White,Black,Natural,Rice Yellow brown and so on.
