The main characteristics of PE：
HDPE is a high crystallinity, non - polar thermoplastic resin.The appearance of the original HDPE is milky white, with a certain degree of translucency in the thin section.PE has excellent resistance to most domestic and industrial chemicals.Certain types of chemicals produce chemical corrosion, such as corrosive oxidants (concentrated nitric acid), aromatic hydrocarbons (xylene), and halogenated hydrocarbons (carbon tetrachloride).The polymer does not absorb moisture and has good waterproof steam, can be used for packaging purposes.HDPE has good electrical properties, especially the high dielectric strength of insulation, which makes it suitable for wire and cable.Medium to high molecular weight classes have excellent impact resistance at room temperature and even at low temperatures of -40f.The unique characteristics of each grade of HDPE are an appropriate combination of four basic variables: density, molecular weight, molecular weight distribution, and additives.Different catalysts are used to produce customized polymers with special properties.These variables are combined to produce different USES of HDPE grade;Achieve a good balance in performance.
