UHMWPE identification methods: Weighing law. Pure ultra high molecular weight polyethylene products made of gravity between 0.93-0.95, lower density, can float on water. If it is not pure polyethylene material, it will sink to the bottom. Temperature measurement. Pure UHMWPE products, at 200 degrees Celsius will not melt, does not deform the high molecular weight polyethylene sheet metal processing, but become soft. If it is not pure UHMWPE material at 200 degrees Celsius there will be deformed. UHMWPE forming: the viscosity of the ultrahigh molecular weight polyethylene (UHMW-PE) in a molten state up to 108Pa * s high molecular weight polyethylene sheet price, poor flowability want high molecular weight polyethylene sheet having a melt index of almost zero, it is difficult with the general machining processing methods. Ultra high molecular weight polyethylene (UHMW-PE) of processing technology has been developing rapidly, through the transformation of ordinary processing equipment, has led to the ultra-high molecular weight polyethylene (UHMW-PE) from the initial pressing - sintering the development of extrusion, blow molding and injection molding and other special methods.
