Machining High Density Polyethylene (HDPE): A Plastics Guide
WEBNov 26, 2019 · Properties of HDPE. HDPE is a high impact, high density crystalline thermoplastic. It also has a low moisture absorption rate and good chemical and corrosion resistance. Compared to its sister polymer LDPE, HDPE offers much greater impact resistance and tensile strength. This polymer has a melt temperature of 266 F (130 C).
