Development of ultra high molecular weight polyethylene History: 2007 2009 - China has gradually become the world's plastics factory quality polyethylene pads, ultra-molecular weight polyethylene industry development is very rapid. In the 1930s it was suggested that the first ultrahigh molecular weight polyethylene fibers on the basic theory. UHMWPE Modified: low, medium molecular weight PE blend. Ultrahigh molecular weight polyethylene (UHMW-PE) and low molecular weight LDPE (molecular weight polyethylene pad 1, 000 to 20 polyethylene pad prices, 000 to 5,000 to 12,000 is preferred) blending can make it moldability significantly improved.
