OEM&ODM engineering plastic delrin sheet pom plate
POM (Polyformaldehyde)
POM (Full-title: Polyformaldehyde), is a engineering plastics of non-side-chain, high density, high crystalline and linear polymer, which is praised “CZPT Steel”, and has extensive superb performances, this kind of as: use-resistance, substantial hardness, anti-impregnant, great rigidity (Tensile modulus of elasticity), chemical stability, isolation resistance and dimensional steadiness. POM has commonly applied in Vehicle industries, digital and electric powered merchandise, commodity, pipeline & fittings, precise equipment and so on, which can be rather of the bronze, Zinc, tin and other metals.
Besides POM-H, is frequently copolymerized with ethylene oxide with each other, in purchase to steer clear of the melting of POM content in the large temperature. POM-H has the greater performances than POM-C in its substantial crystalline, mechanical power and rigidity. And POM-C has the better performances than POM-H in its low melting level, temperature balance, fluxion attribute and machining capacity.
Father more, POM-H+PTFE, which is created from the Delrin POM Resin that maxed Teflon fiber symmetrically, has the lower co-productive of frication, great lubrication, use-resistance, non-creepage resistance.
Car industries: POM has a huge software in vehicle industries, because the mechanical areas produced by POM, which has the positive aspects of large mechanical power, higher hardness, very good dress in-resistance, lower co-successful of friction, simple to preserve, minimizing price and so on, can be employed in vehicles instead of coppery half stalk and planet gear. It not only saving copper components, but also improving support daily life. At the motor gasoline program, factors for hose valves and circumstance cover of radiator, cooling fluid’s standby circumstance, h2o valve, oil box’ include, pump impeller, shell of gasification device and accelerator pedal and so on.
Electronic and electric powered CZPT: because of its lower electrical power consuming, substantial dielectric energy and insulation resistance and digital arc resistance, POM has widely applied in digital and electric CZPT, such as: shell of digital spanner, shell of digital scissors, shell of coal drilling equipment ,take care of of swap, elements also for telephone, wi-fi recorder, video clip tape recorder, tv, pc, electrograph, calculagraph, bracket of recorder tape and so on.
Agricultural machine: portion of manual sprayer, joint and transport portion of seeder, components of milk equipment, shell of irrigation and drainage, valve, joint and bush of drinking water and so on.
Other discipline:
Pharmacy & packing Equipment: transporting screw, world equipment, equipment bar, chain wheel and cushion bar and so on.
CZPT industries: h2o faucet, window frame, clean pot, water tank, pulley for portiere, shell of h2o meter and tie-in of water pipe.
Shade:White,Black,All-natural,Rice Yellow brown and so on.
Measurement:1000X2000X(Thickness:1-200mm),1220X2440X(Thickness:1-200mm)
600X1200X(Thickness:one-200mm)
