HIGH DENSITY POLYETHYLENE (HDPE) is commonly known as low pressure POLYETHYLENE. Compared with LDPE and LLDPE, it has higher temperature resistance, oil resistance, steam permeability resistance and environmental stress cracking resistance. In addition, it has good electrical insulation, impact resistance and cold resistance, which is mainly used in blow molding and injection molding fields.
