美国杜邦POM 500T BK高刚性 耐磨性 热稳定 新能源汽车应用

POM Introduction to the natural environment characteristics of Baoli, Japan:

POM is not resistant to strong alkali and reducing agent, and has certain reliability for enoic acid and weak acid. POM has excellent solvent resistance, can withstand hydrocarbons, aldehydes, hydrocarbons, ethers, automotive gasoline, grease and alkalinity, and can maintain very high organic chemical reliability at high temperature. Small water absorption capacity, good specification and reliability.

The aging resistance of POM is not good. Under the effect of ultraviolet light for a long time, the physical properties are reduced, and the surface layer is delaminated and cracked.

Extrusion formability

Crystalline materials, with narrow melting range, fast melting and condensation, produce crystals when the material temperature is slightly lower than the melting temperature, with medium flow rate and low moisture absorption, which may not be solved by drying.

POM application 1. Automobile industry: manufacturing automobile pump, air receiver parts, oil pipeline, power valve, universal joint 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 as transmission parts such as gears, drive shafts, chains, valves, valve stem nuts, bearings, cams, impellers, rollers, nozzles, guide rails, bushings, pipe joints and mechanical structures.
