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. [1] The longer chain serves to transfer load more effectively to the polymer backbone by ...
Polyethylene or polythene (abbreviated PE; IUPAC name polyethene or poly (methylene)) is the most commonly produced plastic. [7] It is a polymer, primarily used for packaging ( plastic bags, plastic films, geomembranes and containers including bottles, etc.).

IPX 2000 Ultra-high-molecular-weight polyethylene ( IPX 2000, IPX UHMW, IPX UHMW-PE, IPX-UHMW-PE) is an engineered polyethylene compound developed to maintain many traits of UHMW, while increasing abrasion resistance, UV stability and decreasing friction and thermal expansion. [1] IPX UHMW was developed in the early 2000s by material scientists ...
Dec 22, 2015 · Ultrahigh molecular weight polyethylene (UHMWPE), also known as high-modulus polyethylene (HMPE), is a subset of the thermoplastic polyethylene. Polyethylene is a polymer formed from ethylene (C 2 H 4 ), which is a gas having a molecular weight of 28 g/mol. The generic chemical formula for polyethylene is – (C 2 H 4 ) n –, where n is the ...

UHMWPE is synthesized from monomers of ethylene, which are bonded together to form what is called ultra-high-molecular-weight polyethylene (or UHMWPE). These are molecules of polyethylene that are several orders of magnitude longer than familiar high-density polyethylene due to a synthesis process based on metallocene catalysts. In general ...
