UHMWPE Rod can do all kinds of mechanical parts, including food machinery gear, worm, worm, bearings. To do chemical pumps, valves, baffles, filter plate. Medical, but also for heart valves, short orthopedic parts, artificial joints and birth control implant. Do sports skating floor, ground balls, ski board, snowmobile parts. Applications and polyamide, polytetrafluoroethylene similar UHMWPE rods resolution, high molecular weight polyethylene wear resistance than steel rod wear, do gears, bearings, bearings, star wheels, valves, pumps, rails , packing, equipment lining, Slippage board, artificial joints, fiber for bullet-proof vests and ropes. The ultrahigh molecular weight polyethylene (UHMW-PE) was dissolved in a volatile solvent, continuously extruded UHMWPE bar, and then by a thermoreversible gelation / crystallization process, making it a wet gel film, evaporated the film was dried to remove the solvent. Since the formation of the skeleton structure has limited the gel shrinkage, pores generated in the drying process, the maximum porosity biaxially stretched without destroying the complete porous structure. This material can be used as water, oxygen through clothing fabrics and chemical resistance, it can be used as an ultrafiltration / microfiltration membrane, battery separator composite films and so on. Compared with other methods, thus prepared by porous ultrahigh molecular weight polyethylene (UHMW-PE) film has the best pore size, strength and thickness overall performance.
