High Density Polyethylene (HDPE), also known as low-pressure polyethylene, is a translucent film with high crystallinity and a certain degree of non-polar surface. PE has excellent resistance to most of the characteristics of living and industrial chemicals.

HDPE is a highly crystalline, non-polar thermoplastic resin. High-density polyethylene is a white powder granular product, non-toxic, odorless, with a density in the range of 0.940-0.976 g/cm3; crystallinity is 80%-90%, softening point is 125-135 °C, and the use temperature can reach 100. °C; melting temperature 120~160 °C, for materials with larger molecules, the recommended melting temperature range is between 200~250 °C. It has good heat resistance and cold resistance, good chemical stability, high rigidity and toughness, and good mechanical strength. Dielectric properties and environmental stress crack resistance are also good. Hardness, tensile strength and creep are better than low density polyethylene; wear resistance, electrical insulation, toughness and cold resistance are better, but slightly lower than low density insulation; good chemical stability at room temperature Under the conditions, it is insoluble in any organic solvent, resistant to corrosion by acids, alkalis and various salts; the film has low permeability to water vapor and air, low water absorption; poor aging resistance, and environmental crack resistance is not as good as low density polyethylene. In particular, thermal oxidation will degrade its performance. Therefore, the resin needs to be added with an antioxidant and an ultraviolet absorber to improve the improvement. High-density polyethylene film has a low heat distortion temperature under stress, so pay attention to this application.
