Development of ultra high molecular weight polyethylene history: 1964 China successfully developed and put into industrial production; 975 Netherlands use decahydronaphthalene as solvent invented the gel spinning method successfully prepared UHMWPE fiber polyethylene slider, and in 1979 In an application for a patent. Then after a decade of efforts to study polymer polyethylene sliders price, confirmed gel spinning method is an effective method for manufacturing high-strength polyethylene fiber with industrial future. UHMWPE molding: special. In the frozen collagen high molecular weight polyethylene yarn slider working, almost all of the solvent to be contained therein, thus unwrapping state ultrahigh molecular weight polyethylene (UHMW-PE) macromolecular chains are kept well down, and solution temperature drop resulting in frozen colloid ultrahigh molecular weight polyethylene (UHMW-PE) folded chain lamellae form.
