High-density polyethylene (HDPE) or polyethylene high-density (PEHD) is a thermoplastic polymer produced from the monomer ethylene. It is sometimes called "alkathene" or "polythene" when used for HDPE pipes. With a high strength-to-density ratio, HDPE is used in the production of plastic bottles, … See more HDPE is known for its high strength-to-density ratio. The density of HDPE ranges from 930 to 970 kg/m . The standard method to test plastic density is ISO 1183 part 2 (gradient columns), alternatively ISO 1183 part 1 ( See more • HDPE fibers can be spun into rope • Disposable suits; nonwoven HDPE fabric • Housewrap See more • Cross-linked polyethylene (PEX) • HDPE pipe (HDPE) • Low-density polyethylene (LDPE) • Linear low-density polyethylene (LLDPE) See more WebFeb 8, 2024 · Higher molecular weight HDPE typically has a higher density, while lower molecular weight HDPE has a lower density.
