HDPE (high density polyethylene), English full name is High density polyethylene
HDPE is a highly crystalline, non-polar thermoplastic tree
fat. The appearance of the original HDPE milky white, in a slight degree of cross-section was a certain degree of translucent. PE has excellent resistance to most life and industrial chemicals. Certain types of chemicals can cause chemical attack,
Examples are corrosive oxidizers (concentrated nitric acid), aromatic hydrocarbons (xylene) and halogenated hydrocarbons (carbon tetrachloride). The polymer is non-hygroscopic and has good water vapor resistance and can be used for packaging applications. HDPE has good electrical properties,
In particular, dielectric strength is high, making it suitable for use in wire and cable. Medium to high molecular weight grades have excellent impact resistance even at ambient temperatures and even at -40F.
