UHMWPE identification methods: visual methods. The real UHMWPE surface smooth, uniform, smooth and very uniform section density polyethylene wear plate processing, 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 polyethylene wear plate prices, if not pure polyethylene flange end surface crack MILL polymer polyethylene wear, and in turn heating edge phenomenon occurs when the dregs. UHMWPE forming: pressing and sintering. Pressing and sintering ultrahigh molecular weight polyethylene (UHMW-PE) most primitive processing methods. This method is rather low productivity, prone to oxidation and degradation. In order to improve production efficiency, can direct electrical heating method.
