产品说明：

Pomalux CN-SS (Conductive Acetal Copolymer) Stainless-steel-fiber-filled, non-sloughing, dimensionally stable material HDT @ 264 psi of 225° F. This material has relatively high chemical resistance, is extremely strong and stiff, and is an excellent choice for situations where carbon-based conductive fillers are not acceptable. Easily machined with carbide-tipped tooling to tight tolerances.

Advantages:

Low outgassing

Consistent resistivity values

Ease of machining

Good chemical resistance

Applications:

Disk drive assembly fixtures

Semiconductor/electronic components

Telecommunication hardware

Automotive equipment

均聚甲醛的合成一般以甲醛的水溶液在酸的存在下缩合聚合。得到聚合度为100以上的a-聚甲醛，将其加热分解成甲醛气体，经精制和脱水后，通常利用部分预聚合的方法纯化单体，通入含少量引发剂的干燥溶剂中进行聚合。因为水的存在，使分子量显著降低。引发剂可用路易斯酸或碱等。但大多用叔胺进行负离子加成聚合，反应如下：聚甲醛的端基为半缩醛（—CH2OH），当温度高于 100℃ 时，端基易断裂，一般需经端基处理使之稳定化。稳定化处理后可耐热到230 ℃。多聚甲醛可在 170～200 ℃的温度下加工，如注射、挤出、吹塑等。主要用作工程塑料，用于汽车、机械部件等。
