Processing of polyethylene and polypropylene

Due to the presence of tertiary carbon atoms, polypropylene is sensitive to the action of oxygen, especially at elevated temperatures, which makes it more prone to aging than polyethylene and copolymers of ethylene with propylene. Therefore, during processing, stabilizers are added to the polypropylene. Compared with polyethylene, polypropylene has higher strength, heat resistance, oxidation resistance […]

Ultra-strong material for the Arctic developed by Tomsk scientists

Together with foreign colleagues led by Francis Verport, a professor at the University of Ghent (Belgium) and Wuhan University of Technology (China), scientists at the Tomsk Polytechnic University created a polymer that retains its strength even at extremely low temperatures, for example, in extreme Arctic conditions. The main component of the material is a monomer […]
