Russian researchers have developed a new technology for preparing ultra-high molecular weight polyethylene

waste plastic particles 1 are in short supply. The Institute of catalysis of the Siberian Branch of Russia has recently developed a new technology for preparing ultra-high molecular weight polyethylene materials by non melting method

development 2. Elastic stage in this stage, the main purpose of ultra-high molecular polyethylene material is to be applied to extreme conditions in the Arctic, and the polymer material should withstand the low temperature of minus degrees Celsius. When the molecular weight of polyethylene exceeds 1million, some unique properties will appear: high impact resistance, cold resistance, corrosion resistance, wear resistance and low friction coefficient. UHMWPE fiber also has unique quality characteristics. Its products are lighter than water and 1.5 times lighter than aramid fiber products. At present, the annual output of polyethylene in the world is about 100 million tons, of which only 300000 tons (0.3%) are ultra-high molecular weight polyethylene materials, of which only 17000 tons are processed into fibers. The reason for the low output is that the process is complex and the consumption of resources and energy is high. First, dissolve the pellets in boiling organic solvent to get gel. The content of substances in gel that can be used to make fibers is not more than%, and then dry and wire drawing, resulting in high energy consumption and high product cost of the whole process

Siberia branch urged to invest a lot of money in the research and development of antibacterial materials. The new catalyst developed by the research institute adopts the non melting method to prepare ultra-high molecular weight polyethylene materials, opening up a new way to reduce the cost of product preparation. The products can be used in medical products, various textile products and materials for strengthening takeoff and landing runways in cold areas
