HDPE is "High pressure (high density) polyethylene" HDPE is a highly crystalline, non-polar thermoplastic resin. The appearance of the original HDPE is milky white, and it is translucent to a certain extent in the meager section. PE has excellent resistance to most domestic and industrial chemicals. Certain types of chemicals can cause chemical corrosion, such as corrosive oxidants (concentrated nitric acid), aromatic hydrocarbons (xylene) and halogenated hydrocarbons (carbon tetrachloride). The polymer is non-hygroscopic and has good vapor resistance, which can be used for packaging purposes. HDPE has good electrical properties, especially the high dielectric strength of the insulation, making it suitable for wire and cable. Medium to high molecular weight grades have excellent impact resistance at room temperature and even at low temperatures of -40F. The unique characteristic of various grades of HDPE is the proper combination of four basic variables: density, molecular weight, molecular weight distribution and additives. Different catalysts are used to produce custom polymers with special properties. These variables are combined to produce HDPE grades for different uses; Achieve a better balance of performance.

High-density polyethylene is non-toxic, tasteless, odorless white particles with a melting point of about 130℃ and a relative density of 0.941~0.960. It has good heat and cold resistance, good chemical stability, but also has high rigidity and toughness, good mechanical strength. Dielectric properties, environmental stress cracking resistance is also good. Melting temperature 220~260℃. For materials with large molecules, the recommended melting temperature range is between 200 and 250℃.

It is widely used in gas transportation, water supply, sewage, agricultural irrigation, fine particle solid transportation in mines, as well as oil fields, chemical industry and post and telecommunications, especially in gas transportation.

Storage should be away from the fire, heat insulation, the warehouse should be kept dry, clean, no impurities, no sun, rain. Transport should be stored in a clean, dry covered compartment or cabin, without sharp objects such as nails. It is strictly prohibited to mix with flammable aromatic hydrocarbons, halogenated hydrocarbons and other organic solvents.
