六大特种工程塑料之一聚缩醛(polyformaldehyde（POM）)“超钢”或“赛钢”

新材料猎头青儒引士整理编辑

   聚缩醛，外文名polyformaldehyde（POM），化学式(CH2O)n，其是一种高分子聚合物‌，也被称为‌聚甲醛（POM）、‌缩醛树脂或‌聚氧化亚甲基。它是一种热塑性结晶性高分子聚合物，具有高结晶度和优异的力学性能，被誉为“超钢”或“赛钢”

其优良的特性如下

1）具高机械强度和刚性；2）最高的疲劳强度；3）环境抵抗性、耐有机溶剂性佳；4）耐反复冲击性强；5）杰出的电气性质；6）复原性杰出；7）具自光滑性、耐磨性杰出

聚甲醛正在替代一些传统上被金属所占领的市场，如替代锌、黄铜、铝和钢制作许多部件，喷头、水龙头、洗浴盆零件；开关键盘、按钮、音像带卷轴；温控定时器；动力工具，庭园整理工具零件；另外可作为冲浪板等

Thanks to its combination of mechanical properties, thermal stability, and chemical resistance, POM is used in a diverse range of applications.

   Automotive: Within the automotive industry, POM is used to  manufacture various components such as fuel sender units, power steering systems, door lock systems, and many more.

   Electronics: In the electronics sector, the material is used for making connectors, bobbins, switches, and other parts.

Medical: POM’s biocompatibility, sterilizability, and dimensional stability make it a preferred choice for medical device components, including surgical instruments, dialysis machines, and insulin pens.

   Consumer Goods: It is used extensively in the production of mechanical parts for consumer goods such as zippers, watch bracelets, toy components, and musical instruments, among others.
