Polyethylene English referred to as PE, it is ethylene polymer, non-toxic. Easy to color, good chemical stability, cold resistance, radiation resistance, good electrical insulation. It is suitable for food and drug packaging materials, making food utensils, medical equipment, but also for the insulation of the electronics industry.

Polyvinyl chloride is abbreviated as PVC and is a polymer of vinyl chloride. It is chemically stable and resistant to acids, alkalis and some chemicals. It is resistant to moisture, aging and flame. When it is used, the temperature cannot exceed 60°C and it will Aluminum mylar film harden at low temperatures. Polyvinyl chloride is divided into soft plastic and hard plastic. The soft main film is used for packaging materials, rain protection products, agricultural breeding films, etc. It can also be used for insulation of cables and wires, artificial leather products. Rigid, generally made pipes and plates are used as pipes and pipes for transporting corrosion-resistant fluids. The plates are used as linings and floors for various storage tanks.

Cross-linked polyethylene English abbreviation XLPE, is an important technology to improve the performance of PE. Cross-linked modified PE can greatly improve its performance, not only significantly improve the mechanical properties of PE, resistance to environmental stress cracking resistance, chemical corrosion resistance, creep resistance and electrical properties and other comprehensive performance, and The temperature rating of the PE is obviously improved, which can increase the heat-resistant temperature of the PE from 70°C to 90°C, which greatly broadens the application range of the PE. At present, cross-linked polyethylene (XLPE) has been widely used in pipes, films, cable materials and foam products.
