High density polyethylene (HDPE) is a white powder or granular product. It is nontoxic, tasteless, with a crystallinity of 80% - 90% and a softening point of 125-l 35 ℃, service temperature can reach 100 ℃; hardness, tensile strength and creep are better than LDPE; wear resistance, electrical insulation, toughness and cold resistance are better; chemical stability is good, insoluble in any organic solvent at room temperature, corrosion resistance of acid, alkali and various salts; permeability of film to water vapor and air is small, water absorption is low; aging resistance is poor, ring resistance is poor The environmental stress cracking property of LDPE is not as good as that of LDPE, especially the degradation of its performance due to thermal oxidation. Therefore, antioxidant and ultraviolet absorbent should be added to the resin to improve the deficiency. High density polyethylene film has low temperature of thermal deformation under stress, so attention should be paid to its application.
With the rapid development of polymer materials science and technology, the deepening of the development and utilization of plastic pipes, and the continuous improvement of production technology, plastic pipes show their outstanding performance incisively and vividly. Today, plastic pipes are no longer mistaken as "cheap substitutes" for metal pipes. In this revolution, polyethylene pipeline is favored by many people, which is increasingly shining. It is widely used in gas transportation, water supply, sewage, agricultural irrigation, fine particle solid transportation in mines, oil fields, chemical industry, post and telecommunications and other fields, especially in gas transportation.
