长期供应 POM 美国杜邦 Delrin DE7031 耐溶剂 阻燃 抗磨损

杜邦POM Delrin介绍

DELRIN聚甲醛产品具有独特的粘接强度、硬度、不易弯曲、尺寸稳定性、韧性、耐疲劳性、耐溶剂、阻燃、抗磨损、耐用、低摩擦等特点，因此，它可以被用来填补金属和一般塑料之间的不足。

POM（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。

聚甲醛是一种表面光滑、有光泽的硬而致密的材料，淡黄或白色，薄壁部分呈半透明。燃烧特性为容易燃烧，离火后继续燃烧，火焰上端呈黄色，下端呈蓝色，发生熔融滴落，有强烈的刺激性甲醛味、鱼腥臭。聚甲醛为白色粉末，一般不透明，着色性好，比重1.41-1.43克/立方厘米，成型收缩率1.2-3.0%，成型温度170-200℃，干燥条件80-90℃2小时。POM的长期耐热性能不高，但短期可达到160℃，其中均聚POM短期耐热比共聚POM高10℃以上，但长期耐热共聚POM反而比均聚POM高10℃左右。可在-40℃～100℃温度范围内长期使用。POM极易分解，分解温度为280度，分解时有刺激性和腐蚀性气体发生。故模具钢材宜选用耐腐蚀性的材料制作。
