POM(聚甲醛)可分为均聚甲醛和共聚甲醛两种。两者的重要区别是:均聚甲醛密度、结晶度、熔点都高,但热稳定性差,加工温度范围窄(约10℃),对酸碱稳定性略低;而共聚甲醛密度、结晶度、熔点、强度都较低,但热稳定性好,不易分解,加工温度范围宽(约50℃),对酸碱稳定性较好。是具有优异的综合性能的工程塑料。
POM is the only one of the five engineering plastics that can be manufactured in large quantities based on a variety of raw material routes, starting from the source, not too long process. POM is a deep-processing product of methanol and an extremely important downstream product of carbon-chemistry in the coal chemical product chain. POM is an important general-purpose thermoplastic engineering plastics. Because of its high tensile strength, low density, self-lubrication, corrosion resistance and excellent weather resistance, POM is a high-tech, high-input and high value-added product. Its production and processing tools have high technical content and economic added value
