P0M简介
(聚甲醛)(赛钢~特灵) 英文名称:Polyoxymethylene(Polyformaldehyde) P0M(聚甲醛树脂)定义:聚甲醛是一种没有侧链、高密度、高结晶性的线型聚合物。按其分子链中化学结构的不同,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。有良好的物理、机械和化学性能,尤其是有优异的耐摩擦性能。俗称赛钢或夺钢,为第三大通用塑料。 适于制作减磨耐磨零件,传动零件,以及化工,仪表等零件。

Huayun Plastic company features: (1) POM can be processed without drying, good in the process of preheating about 800, the product size stability is good. (2) POM is processed at a very narrow temperature of 0.215, which will decompose when it stays in the barrel for a little longer time or when the temperature exceeds 220. (3) the pressure of POM injection should be close to that of injection to reduce the pressure drop. Screw speed can not be too high, residual less; (4) POM product shrinkage rate is large, easy to produce shrinkage or deformation. Pom Specific Heat, high mold temperature, product demoulding is very hot, need to prevent burns fingers. (5) POM should be processed under the conditions of "medium pressure, medium speed, low material temperature and high mould temperature" , precision products need to be molded with control die temperature 6 with high mechanical strength and rigidity 7 high fatigue strength 8 environmental resistance, good resistance to organic solvents 9 good resistance to repeated impact, good electrical properties, good recovery, with self-lubrication, good wear resistance, dimensional stability.
