HDPE resin, the full name is high density polyethylene, is a high-density thermoplastic polyolefin produced by copolymerization of ethylene. High density polyethylene resin has better hardness, tensile strength and creep than low-density polyethylene. Meanwhile, it also has the advantages of good wear resistance, electrical insulation, toughness and cold resistance, good chemical stability, low permeability of the film to water vapor and air, as well as low water absorption. At room temperature, HDPE resin is insoluble in any organic solvent and resistant to acid, alkali and various salts.
However, its aging resistance is poor, and its environmental stress cracking resistance is not as good as that of LLDPE resin, especially thermal oxidation will reduce its performance. Therefore, antioxidants and ultraviolet absorbers must be added to the resin to improve this deficiency. High density polyethylene (HDPE) film has a lower heat distortion temperature under stress.

1. HDPE is a highly crystalline, non-polar thermoplastic resin.
2. The appearance of the original HDPE resin is milky white, and the thin section is translucent to a certain extent.
3. HDPE resin has excellent resistance to most domestic and industrial chemicals.
4.The polymer is non-hygroscopic and has good water vapor resistance for packaging purposes.
5. High density polyethylene (HDPE) has good electrical properties, especially the high dielectric strength of the insulation, making it very suitable for wires and cables.
6. Medium to high molecular weight grades HDPE have excellent impact resistance at room temperature or even down to -40F.
7. The unique properties of the various grades of HDPE are the proper combination of four fundamental variables (density, molecular weight, molecular weight distribution and additives). Different catalysts are used to produce polymers with tailored special properties. These variables combine to produce HDPE grades for different uses, achieving an optimal balance of properties.
8. HDPE recycling. HDPE high density polyethylene is the fastest growing resin in the plastic raw material recycling market. This is mainly due to its ease of reprocessing, minimal degradation characteristics and its wide application in packaging applications.
