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.
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)

Ultra-high-molecular-weight polyethylene ( UHMWPE ), also known as high-modulus polyethylene ( HMPE) or high-performance polyethylene ( HPPE ), is a thermoplastic. It has extremely long chains, with molecular weight numbering in the millions, usually between 2 and 6 million.
HDPE has SPI resin ID code 2. 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 ...
PE-UHPM, polyéthylène de masse molaire très élevée (UHMWPE, ultra-high-molecular-weight polyethylene ou PE-UHMW selon la norme EN ISO 1043-1) ; réticulés : les polyéthylènes réticulés (PE-R, dits aussi PEX ou XLPE, pour cross-linked polyethylene) sont presque tous faits à partir de polyéthylène à haute densité (HDPE), on les désigne alors :
- poly(méthylène)

UHMWPE pour ultra high molecular weight polyethylene (parfois abrégé en UHMW), également connu sous le nom de polyéthylène à haut module (HMPE, high modulus polyethylene) ou de polyéthylène haute performance (HPPE, high performance polyethylene ). Présentation.
Jul 2, 2021 · July 2, 2021. 5:49 pm. The UHMWPE fiber (Ultra High Molecular Weight Polyethylene Yarn) is 15 times stronger than steel and 40% stronger than aramid when weight for weight basis. It is the strongest yarn today for making cut-resistance gloves, high-strength ropes, and bulletproof fabrics.
