History of the development of ultra high molecular weight polyethylene: ultra-high molecular weight polyethylene pipe in China in 2001 by the National Science and Technology Ministry of Science and Technology National Science of the word document (2000) No. 056 focus on promotion of ultra high molecular weight polyethylene wear block Prices , is a chemical class of new materials and new products. State Planning Commission of Science and Technology ultrahigh molecular weight polyethylene pipe project as a high-tech industry is currently focused on priority development areas. UHMWPE modified: processing. In order to solve the ultra-high molecular weight polyethylene (UHMW-PE) of ultra high molecular weight polyethylene processing problems wearable pieces processing, in addition to ordinary molding machine specially designed, but also of the resin formulations improve: blended with other resins or join flow modifiers, so that it can molding in the ordinary extruders and injection molding machines.
