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. UHMWPE RF: RF processing ultra high molecular weight polyethylene (UHMW-PE) is a new method for processing coal bunker liner polyethylene prices, it is the ultra-high molecular weight polyethylene (UHMW-PE) powder and high dielectric loss carbon black powder were uniformly mixed together Usually polyethylene coal bin liner, RF radiation, heat generated allows ultra high molecular weight polyethylene (UHMW-PE) powder surface is softened, so that it can Consolidation under a certain pressure.
