PE：聚乙烯（polyethylene ，简称PE）的缩写。
聚乙烯（polyethylene ，简称PE）是乙烯经聚合制得的一种热塑性树脂。
在工业上，也包括乙烯与少量α-烯烃的共聚物。聚乙烯无臭，无毒，手感似蜡，具有优良的耐低温性能（最低使用温度可达-100~-70°C），化学稳定性好，能耐大多数酸碱的侵蚀（不耐具有氧化性质的酸）。常温下不溶于一般溶剂，吸水性小，电绝缘性优良。
2017年10月27日，世界卫生组织国际癌症研究机构公布的致癌物清单初步整理参考，聚乙烯在3类致癌物清单中。
扩展资料：
聚乙烯化学分类：
聚乙烯依聚合方法、分子量高低、链结构之不同，分高密度聚乙烯、低密度聚乙烯及线性低密度聚乙烯。
1，低密度聚乙烯(LOW DENSITY POLYETHYLENE，LDPE)俗称高压聚乙烯，因密度较低，材质最软，主要用在塑胶袋、农业用膜等。
2，高密度聚乙烯(HIGH DENSITY POLYETHYLENE，HDPE)俗称低压聚乙烯，与LDPE及LLDPE相较，有较高之耐温、耐油性、耐蒸汽渗透性及抗环境应力开裂性，此外电绝缘性和抗冲击性及耐寒性能很好，主要应用于吹塑、注塑等领域。
3，线型低密度聚乙烯(LINEAR LOW DENSITY POLYETHYLENE，LLDPE)，则是乙烯与少量高级 -烯烃在催化剂存在下聚合而成之共聚物。
LLDPE外观与LDPE相似，透明性较差些，惟表面光泽好，具有低温韧性、高模量、抗弯曲和耐应力开裂性，低温下抗冲击强度较佳等优点。
LLDPE应用领域几乎已渗透到所有LDPE市场。现阶段LLDPE和HDPE处于生命周期的成长阶段；LDPE则在1980代末逐渐进入发展成熟期，世界上已少有LDPE设备投产。
聚乙烯可用挤出、注射、模塑、吹塑和熔纺等方法成型，广泛应用于工业、农业、包装及日常工业中。
在中国应用相当广泛，薄膜是其最大的用户，约消耗低密度聚乙烯77%，高密度聚乙烯的18%，另外，注塑制品、电线电缆、中空制品等都在其消费结构中占有较大的比例，在塑料工业中占有举足轻重的地位。
