History of the development of ultra high molecular weight polyethylene: the emergence of plasticized gel spinning method and spinning method of making UHMWPE major breakthrough in technology; 70s of the last century, a high molecular polyethylene pad factory, Leeds University, UK First The successful development of a molecular weight of 100,000 molecular weight polyethylene fibers. UHMWPE forming: heat treatment. The ultra high molecular weight polyethylene (UHMW-PE) resin powder between 140 ℃ ~ 275 ℃ short-term heating 1min ~ 30min found ultrahigh molecular weight polyethylene (UHMW-PE) surprisingly certain physical properties greatly improved.
