HDPE is known for its high strength-to-density ratio. The density of HDPE ranges from 930 to 970 kg/m3. Although the density of HDPE is only marginally higher than that of low-density polyethylene, HDPE has little branching, giving it stronger intermolecular forces and tensile strength (38 MPa versus 21 MPa) than LDPE. The difference in strength ex...
HDPE fibers can be spun into ropeDisposable suits; nonwoven HDPE fabricPlastic mailing envelopesIndustrial production of HDPE from ethylene happens through either Ziegler-Natta polymerization or the Phillips slurry process.
