聚丙烯是丙烯加聚反应而成的聚合物。与聚bai丙烯（PP均聚物）du相比，无规共聚聚zhi丙烯改进了光学性能，提高了抗冲击性能，增加了挠性，降低了熔化温度，从而也降低了热熔接温度；同时在化学稳定性、水蒸汽隔离性能和器官感觉性能方面与均聚物基本相同。

聚丙烯广泛应用于服装、毛毯等纤维制品、医疗器械、汽车、自行车、零件、输送管道、化工容器等生产，也用于食品、药品包装。

共聚丙烯应用于吹塑、注塑、挤塑、薄膜和片材挤压加工领域，常用于自来水管、食品包装材料、医药包装材料和日常消费品。

LyondellBasell’s expertise in polyethylene technology has resulted in the development of products that copolymerize ethylene with vinyl acetate to produce resins used in specialized applications. Ultratheneethylene vinyl acetate (EVA) copolymers combine many of the advantages of low-density polyethylene (LDPE), such as clarity and toughness, with outstanding flexibility, low-temperature performance and lower heat seal initiation temperatures.
