产品详细信息聚甲醛POM颗粒聚合物

所有聚甲醛都是半透明或不透明的黄色或白色颗粒，表面光滑，有光泽的坚硬致密材料，薄的

墙体产品半透明星状半透明

根据分子链中化学结构的不同，可分为均聚物和共聚物。两者之间的重要区别是：均聚

甲醛密度、结晶度、熔点高，但热稳定性差，加工温度范围（约10°），酸碱稳定性略低：共聚物甲醛密度、结晶度、熔点、强度低，但热稳定性好，不易分解，加工温度范围宽（50°C），对酸碱稳定性好

在注射成型过程中，至少应达到中等注射速度。如果注射速度太慢，模具或熔融材料温度太低，产品表面容易出现细孔

Physicochemical properties

POM- polyformaldehyde (Polyoxymethylene) in English name: Acetal resin, Polyoxymethylene, Polyacetal.

POM is a linear and highly crystalline polymer with no side base, high density and high crystallization. It has high elastic modulus, high hardness and stiffness. It can be used at -40-100°C for a long time, and is resistant to repeated impact with few strength changes. The strength is little affected by temperature and temperature change, and the creep is small. Has good comprehensive performance, has the most superior thermoplastic material fatigue resistance, outstanding creep resistance, good electrical properties.

All polyformaldehyde is translucent or opaque yellowish or white particles, smooth surface, glossy hard and dense material, thin

Wall products translucent star translucent.

According to the different chemical structures in the molecular chain, it can be divided into homopolymer and copolymer. The important difference between the two is: homopolymerization

Formaldehyde density, crystallinity, melting point are high, but the thermal stability is poor, processing temperature range (about 10°), the acid and base stability is slightly

Low: copolymer formaldehyde density, crystallinity, melting point, strength are low, but good thermal stability, not easy to decompose, processing temperature

Wide range (50°C), good stability to acid and base.

At least medium injection speed should be achieved during injection molding. If the injection speed is too slow, the mold or molten material temperature is too low, the product surface

Fine pores tend to appear.
