聚甲醛(POM)的学名
它是以甲醛为原料聚合而成。POM-H(聚甲醛)和POM-K(聚甲醛)具有高密度和高结晶度聚甲醛是一种无侧链、高密度、高结晶度的线性聚合物。根据其分子链中化学结构的不同,可分为两类:均聚甲醛和共聚甲醛两者之间的重要区别是:均聚甲醛具有高密度、结晶度和熔点,但热稳定性差,加工温度范围窄(约10°C),酸碱稳定性略低共聚甲醛具有低密度、结晶度、熔点和强度,但具有良好的热稳定性,不易分解,加工温度范围宽(约50°C),并具有良好的酸碱稳定性。是一种综合性能优异的工程塑料

POM: The scientific name of polyoxymethylene(POM).
It is obtained by polymerization of formaldehyde as raw materials. POM-H (polyoxymethylene) and POM-K (polyoxymethylene) are high density and high crystallinity.
Polyoxymethylene is a linear polymer with no side chains, high density and high crystallinity. According to the different chemical structure in its molecular chain, it can be divided into two types: homopolyoxymethylene and copolyoxymethylene.
The important difference between the two is: homopolyoxymethylene has high density, crystallinity, and melting point, but poor thermal stability, narrow processing temperature range (about 10°C), and slightly lower acid-base stability;
The copolyformaldehyde has low density, crystallinity, melting point and strength, but it has good thermal stability, is not easy to decompose, has a wide processing temperature range (about 50°C), and has good acid-base stability. It is an engineering plastic with excellent comprehensive properties.
