PE分子式：CAS号：性质：由乙烯均聚以及与少量α-烯烃共聚制得的乳白色、半透明的热塑性塑料。密度0.86～0.96g/cm3，按密度区分有低密度聚乙烯(也包括线性低密度聚乙烯)、超低密度聚乙烯(特低密度聚乙烯)、中密度聚乙烯、高密度聚乙烯等。无味、无毒。耐化学药品，常温下不溶于溶剂。耐低温，最低使用温度-70～-100℃。电绝缘性好，吸水率低。物理机械性能因密度而异。工业上低密度聚乙烯主要采用高压(110～200MPa)、高温(150～300℃)自由基聚合。其他则用低压配位聚合，有时同一套装置可生产密度0.87～0.96g/cm3的聚乙烯产品，称全密度聚乙烯工艺技术。聚乙烯可加工制成薄膜、电线电缆护套、管材、各种中空制品、注塑制品、纤维等。广泛用于农业、包装、电子电气、机械、汽车、日用杂品等方面。
