UHMWPE forming: a porous membrane. The ultra-high molecular weight polyethylene (UHMW-PE) was dissolved in a volatile solvent, the polymer polyethylene shaped, continuous extrusion, ultra high molecular weight polyethylene shaped, and then by a thermally reversible gel / crystallization process, polyethylene profiled member, making it a wet gel film, the film was dried and the solvent was distilled off. 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.
