Self-lubricating UHMWPE extruded: external lubricant mainly higher fatty acids, complex lipids, silicone resin, paraffin and other low molecular weight resins. Prior to extrusion (injection) process, first lubricant processing aid is mixed together with other materials in the price of coal bunker liner retardant, flame coal bunker liner production process, the material in the lubricant leaking Buying flame coal bin liner, to form a lubricating layer, to achieve self-lubricating extrusion (injection). UHMWPE heat treatment: the ultra-high molecular weight polyethylene (UHMW-PE) resin powder between 140 ℃ ~ 275 ℃ for short-term heating 1min ~ 30min and found the ultra-high molecular weight polyethylene (UHMW-PE) some unexpectedly greatly improved physical properties.
