HDPE stands for high density polyethylene. It's a generally-used thermoplastic resin made from pure gas or obtained by way of refining petroleum. Polyethylene can endure a low- or excessive-strain process of forming polymer chains (polymerization). High-density polyethylene has longer chains with fewer aspect branches that gives higher crystallinity, and thus greater stiffness, hardness, energy and heat [...]
