HDPE ALATHON M5562

基本特性：高密度聚乙烯是一种不透明白色腊状材料，比重比水轻，比重为0.941~0.960，柔软而且有韧性，但比LDPE略硬，也略能伸长，无毒，无味。

燃烧特性：易燃，离火后能继续燃烧，火焰上端呈黄色，下端呈蓝色，燃烧时会熔融，有液体滴落，无黑烟冒出，同时，发出石蜡燃烧时发出的气味。

主要优点：耐酸碱，耐有机溶剂，电绝缘性优良，低温时，仍能保持一定的韧性。表面硬度，拉伸强度，刚性等机械强度都高于LDPE，接近于PP，比PP韧，但表面光洁度不如PP。

主要缺点：机械性能差，透气差，易变形，易老化，易发脆，脆性低于PP，易应力开裂，表面硬度低，易刮伤。难印刷，印刷时，需进行表面放电处理，不能电镀，表面无光泽。

主要用途：

高密度聚乙烯树脂可采用注射、挤出、吹塑和旋转成型等方法成型塑料制品。采用注射成型可成型出各种类型的容器、工业配件、医用品、玩具、壳体、瓶塞和护罩等制品。采用吹塑成型可成型各种中空容器、超薄型薄膜等。采用挤出成型可成型管材、拉伸条带、捆扎带、单丝、电线和电缆护套等。

另外，还可成型建筑用装饰板、百叶窗、合成木材、合成纸、合成膜和成型钙塑制品等。
