  2.聚乙烯:常用聚乙烯可分为低密度聚乙烯(LDPE)、高密度聚乙烯(HD特种塑料PE)和线性低密度聚乙烯(LLDPE)。三者当中,HDPE有较好的热性能、电性能和机械性能,而LDPE和LLDPE有较好的柔韧性、冲击性能、成膜性等。
  Polyethylene: commonly used polyethylene can be divided into low density polyethylene (LDPE), high density polyethylene special plastic PE (HD) and linear low density polyethylene (LLDPE). Among the three, HDPE has good thermal performance, electricity performance and mechanical properties, and the LDPE and LLDPE has better flexibility and impact performance, film, etc.
