High density polyethylene (HDPE) for non-toxic, tasteless, no smelly white particles, melting point is about 130 ° C, relative density of 0.941 ~ 0.960. It has good heat resistance and cold resistance, chemical stability, but also has high rigidity and toughness, good mechanical strength. Dielectric properties, environmental stress cracking resistance sex also is good.
