HDPE is a non polar thermoplastic plastic with high crystallinity and perfect electrical properties,especially the high insulation dielectric strengh.This polymer is non-hygroscopic which can be used to packing with good waterproof steam.HDPE with Middle to high molecure weight have good impact resistance at normal temperature even in the zero 40 degree Celisius.
