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 law UHMWPE board prices, temperature measurements Buying ultra high molecular weight polyethylene plate, visual method, the edge test. UHMWPE plate impact strength improved with increasing molecular weight of the ultra-high molecular weight polyethylene mill, reaches a maximum when the molecular weight of 1,500,000, and then continue to rise with the molecular weight gradually decreased. It is worth noting that it in liquid nitrogen (-195 ℃) can maintain excellent impact strength, this feature is not found in other plastics. In addition, it is higher in the repeated impact surface hardness.
