Ultra high molecular weight polyethylene (UHMW-PE) identification method: ultra high molecular weight polyethylene is a polymer compound, difficult to process, and with superior wear resistance, self-lubricating, high strength, chemical stability, anti-aging properties. Weighing rule, temperature measurement, visual method UHMWPE board price, margin test. UHMWPE identification methods: visual methods. The real UHMWPE surface smooth, uniform, smooth and very uniform density section, if not pure polyethylene material is faded and uneven density. Edge test. Pure high molecular weight polyethylene flange end face of the round, uniform, smooth, if not pure polyethylene flange end surface cracks, and when heated after flanging dregs phenomenon occurs.
