HDPE is a highly crystalline, non-polar thermoplastic resin. High-density polyethylene is a white powder granular product, non-toxic and odorless, with a density in the range of 0.940~0.976 g/cm3; a crystallinity of 80%~90%, a softening point of 125~135°C, and a service temperature of up to 100 ºC; melting temperature is 120~160ºC. For materials with larger molecules, the recommended melting temperature range is between 200~250ºC. It has good heat resistance and cold resistance, good chemical stability, high rigidity and toughness, and good mechanical strength. The dielectric properties and environmental stress cracking resistance are also good. The hardness, tensile strength and creep properties are better than low-density polyethylene; the wear resistance, electrical insulation, toughness and cold resistance are all better, but slightly worse than low-density insulation; the chemical stability is good, at room temperature Under certain conditions, it is insoluble in any organic solvent and resistant to corrosion by acids, alkalis and various salts; the film has low permeability to water vapor and air and low water absorption; poor aging resistance

HDPE (high-density polyethylene) has a wide range of applications. The following are its main application fields:
Pipeline system: HDPE pipes are widely used in water, gas and oil transportation fields due to their pressure resistance and impact resistance.
Industrial containers and storage tanks: The high strength and durability of HDPE make it suitable for manufacturing industrial containers, storage tanks and pallets that need to withstand high loads and frequent use.
Anti-corrosion linings and coatings: The chemical resistance of HDPE makes it suitable for manufacturing anti-corrosion linings and coatings to protect other materials from chemical corrosion
Water treatment and Marine engineering: The low water absorption rate and corrosion resistance of HDPE make it widely used in water treatment and Marine engineering, such as in the manufacture of water tanks, floating Bridges and ocean buoys.
In the field of electronics and electrical engineering: The electrical insulation properties of HDPE make it used as the insulation layer of cables and wires, as well as the casings and components of electronic devices.
Construction and infrastructure: HDPE plays a role in the construction and infrastructure sectors, for instance, as a building material such as flooring and wall panels.
Automotive parts: HDPE is used to manufacture automotive parts such as bumpers and interior parts due to its light weight and impact resistance
