HDPE is the abbreviation of High Density Polyethylene, which is a kind of non-polar thermoplastic resin with high crystallinity.
PE has excellent resistance to most household and industrial chemicals. The appearance of the original HDPE is milky white, with a certain degree of translucency in the thin section.
HDPE has a melting point of about 130 ° C and a relative density of 0.941 to 0.960. It has good heat resistance and cold resistance.
Compared with low-density insulation, it is slightly worse; good chemical stability, insoluble in any organic solvent at room temperature, resistant to corrosion by acids, alkalis and various salts.
