High-density polyethylene (HDPE) is a polyethylene thermoplastic made from petroleum. The mass density of high-density polyethylene can range from 0.93 to 0.97 g/cm³. Although the density of HDPE is only slightly higher than that of low-density polyethylene, HDPE has little branching, giving it stronger intermolecular forces and tensile strength than LDPE.
