WebHigh-density polyethylene. 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. [1] With a high strength-to-density ratio, HDPE is used in the production of plastic bottles, corrosion ... Ultra-high-molecular-weight polyethylene (UHMWPE, UHMW) is a subset of the thermoplastic polyethylene. Also known as high-modulus polyethylene, (HMPE), it has extremely long chains, with a molecular mass usually between 3.5 and 7.5 million amu. The longer chain serves to transfer load more effectively to … See more Polymerization of UHMWPE was commercialized in the 1950s by Ruhrchemie AG, which has changed names over the years.
