Ultrahigh molecular weight polyethylene having a molecular weight of more than 1.5 million linear polyethylene unbranched. Formula: - (- CH2-CH2 -) - n-, density: 0.920 ~ 0.964g / cm3. Heat distortion temperature (0.46MPa) 85 ℃, m.p. 130 ~ 136 ℃. Ultra high molecular weight polyethylene (UHMW-PE) is a thermoplastic engineering plastic with excellent overall performance of a linear structure. UHMWPE forming: RF. RF processing ultra high molecular weight polyethylene (UHMW-PE) is a new method for processing coal bunker supply polyethylene liner wear, it is the ultra-high molecular weight polyethylene (UHMW-PE) powder and dielectric loss High carbon black powder were uniformly mixed together polyethylene coal bin liner wear production, radio frequency radiation, the heat generated can ultrahigh molecular weight polyethylene (UHMW-PE) powder to soften the surface occurs, so that it can Consolidation under pressure.
