Talking about the development space of ultra-high molecular weight polyethylene special-shaped parts

The material of UHMWPE shaped parts is mainly UHMWPE, and its mechanical properties are higher than that of ordinary high-density polyethylene. The dielectric properties of the polymer polyethylene liner are also good in environmental stress cracking resistance. Melting temperature 220~260C. For materials with larger molecules, the recommended melting temperature range is between 200 and 250C. It has excellent impact resistance, stress crack resistance, high temperature creep resistance, low friction coefficient, self-lubrication, excellent chemical corrosion resistance, fatigue resistance, noise resistance, nuclear radiation resistance, etc.
In recent years, with the continuous breakthrough of ultra-high molecular weight polyethylene processing technology, ultra-high molecular weight polyethylene special-shaped products have been applied in general machinery, food machinery, chemical industry, medical equipment, entertainment products, etc. It has good heat resistance and cold resistance, good chemical stability, high rigidity and toughness, and good mechanical strength. Ultra-high molecular weight polyethylene profiles are also used in small snow blowers, deposits, and cross-section slide rail products for vacuum dryers. With the development of processing technology, the application field of ultra-high molecular weight polyethylene will continue to expand.
Ultra-high molecular weight polyethylene special-shaped parts have the characteristics of wear resistance, corrosion resistance, impact resistance, low temperature resistance, self-lubrication, etc. Because of these characteristics, various special-shaped parts processed with it as the base material are widely used. Coal bunker liner is very difficult to process due to the entangled molecular chain of UHMWPE, extremely high viscosity and almost no fluidity. It is difficult to shape the product with general processing equipment. Such as papermaking enterprises’ water absorption box (components: high water tank, water storage tank, low water tank) panel, coking plant slag remover, coal mine enterprise rope stabilizer, polyethylene rods on conveying devices, polyethylene gears, etc.
In China’s rapidly developing economy, ultra-high molecular weight polyethylene has become one of the irreplaceable materials for the production of high molecular weight polyethylene special-shaped parts. However, the special-shaped parts also play a top priority. Occupy a large market space. At present, the demand for UHMWPE special-shaped parts has increased significantly, and it occupies a certain share in the industry.
