HDPE - definition of HDPE by The Free Dictionary
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 WebLow-density polyethylene (LDPE) is a thermoplastic made from the monomer ethylene.It was the first grade of polyethylene, produced in 1933 by Imperial Chemical Industries (ICI) using a high pressure process via … イデアシステム 株
High-density polyethylene Definition & Facts Britannica
Polyethylene is classified by its density and branching. Its mechanical properties depend significantly on variables such as the extent and type of branching, the crystal structure, and the molecular weight. There are several types of polyethylene: • Ultra-high-molecular-weight polyethylene (UHMWPE) WebLow Density Polyethylene (LDPE) High degree of short and long chain branching Density - 30.910–0.940 g/cm Lower tensile strength and increased ductility Free radical … WebAug 16, 2024 · HDPE pipe has a very low tolerance to deposit formation, and consequently the installation of it in the pipeline is very simple. When compared with other systems with metals, HDPE is one of the most resistant to corrosion and deposit forming elements in the long term. 8. Flexibility to speed installations. イデアシステム株式会社
