UHMWPE is used as a new type of non-metallic materials to build ultra high molecular weight polyethylene wear block, a molecular weight of 1 million or more polyethylene. In recent years, this new type of plastic widely used in Europe and the United States to ultra high molecular weight polyethylene wear block, demand is growing. The same quality UHMWPE wearable pieces, in application of ultra high molecular weight polyethylene products are increasingly being used ultra high molecular weight polyethylene wear block processing, high-tech industry of China "second five" plan "priority development key field guide "to promote the project. Ultrahigh molecular weight polyethylene liner is more than one million molecular weight polyethylene. Polyethylene liner processing: pressing sintering is UHMW- PE first processing method, it is the ultrahigh molecular weight polyethylene liner powder is placed in a mold, pressing into blanks have a certain strength and density, and then at a predetermined temperature sintering.
