POM Introduction to the natural environment characteristics ofBaoli, Japan:
POM is not resistant to strong alkali and reducing agent, andhas certain reliability for enoic acid and weak acid. POM hasexcellent solvent resistance, can withstand hydrocarbons,aldehydes, hydrocarbons, ethers, automotive gasoline, grease andalkalinity, and can maintain very high organic chemical reliabilityat high temperature. Small water absorption capacity, goodspecification and reliability.
The aging resistance of POM is not good. Under the effect ofultraviolet light for a long time, the physical properties arereduced, and the surface layer is delaminated and cracked.
Extrusion formability
Crystalline materials, with narrow melting range, fast meltingand condensation, produce crystals when the material temperature isslightly lower than the melting temperature, with medium flow rateand low moisture absorption, which may not be solved by drying.
POM application 1. Automobile industry: manufacturing automobilepump, air receiver parts, oil pipeline, power valve, universaljoint bearing, motor gear, crankshaft, handle, instrument panel,car window lift device, electric switch, safety belt buckle,etc.
2. In the machinery manufacturing industry, it is widely used astransmission parts such as gears, drive shafts, chains, valves,valve stem nuts, bearings, cams, impellers, rollers, nozzles, guiderails, bushings, pipe joints and mechanical structures.
