PE pipes are widely used in various fields. Among them, water supply pipes and gas pipes are its two largest application markets. PE resin is formed by the polymerization of monomer ethylene. Due to different polymerization reaction conditions such as pressure and temperature during polymerization, different densities of resins can be obtained, resulting in high-density polyethylene, medium density polyethylene, and low-density polyethylene. When processing different types of PE pipes, different resin grades are selected based on their application conditions, and the requirements for extruders and molds also vary.
