UHMWPE sheet extrusion molding process in the past, a single-screw, twin-screw extruder molding. But along with the increase of science and technology, we have also changed for low compression ratio of single-screw extrusion technology and equipment, extrusion molded products of various shapes. Under normal circumstances, the process of the UHMWPE sheet material for cutting pension, profiles, conveyor line rail, railing snowboard movable parts, automotive cable casing, connectors, fluid delivery pipe liner bag and so on. UHMWPE sheet of paper and wastewater treatment industry bearings, dehydration bottom, slide and filtering devices. Cell separator using a porous polymer polyethylene sheet, which reflects the excellent corrosion resistance materials. High strength polymer polyethylene fiber sheet is a newly developed material currently in development. Sailboat race is used in the fiber, which requires the use of high performance composite materials, namely light weight, anti-mildew and is made of parts with dimensional stability. Such fibers are also used as a reinforcing material of the composite structure. UHMWPE wear plastic sheet Habitat crown, and over some of the metal, ultra-high molecular weight polyethylene sheet compared with other engineering plastics, polymer polyethylene wear index mortar board is only 1/5 of PA66 , HEPE and PVC 1/10; compared with metal, carbon steel 1/7, 1/27 brass such a high wear resistance, so experiment with ordinary plastic wear it difficult to test the degree of wear therefore designed a mortar wear test device.
