UHMWPE applications: ultra-high molecular weight polyethylene which can be made directly ropes, cables and nets and various fabrics: bullet-proof vests and clothing, cut-resistant gloves and other wear-resistant polymer processing coal bin liner, including bullet-proof vests better than Kevlar bulletproof. The international community has high molecular weight polyethylene (UHMW-PE) fiber woven into ropes of different fineness of coal bunker liner wear-resistant polymer prices, instead of the traditional steel cables and synthetic fiber rope. Self-lubricating extruded UHMWPE: ultra high molecular weight polyethylene (UHMW-PE) of the self-lubricating extrusion (injection) is added in an appropriate amount of external lubricant, to reduce the polymer molecules with the mold wall friction shear, improving the uniformity of the material flow and releasing effect and extrusion quality.
