The raw material tape is also called polytetrafluoroethylene tape, and polytetrafluoroethylene is a polymer of tetrafluoroethylene, abbreviated as PTFE in English. The raw material tape is an auxiliary product commonly used in the installation of liquid pipelines. It is used at the connection of pipe fittings to enhance the airtightness of the connection of the pipeline. Polytetrafluoroethylene (F4, PTFE) has a series of excellent performance: high temperature resistance - long-term use temperature of 200~260 degrees, low temperature resistance - still soft at -100 degrees; corrosion resistance - resistance to aqua regia and all organic solvents; Weather resistance—extremely long aging life in plastics; high lubricity—with the smallest coefficient of friction (0.04) in plastics; non-stick—with the smallest surface tension in solid materials without sticking to anything; non-toxic—with physiological Inert; excellent electrical properties, ideal for Class C insulation. PTFE materials are widely used in important departments such as national defense and military industry, atomic energy, petroleum, radio, electrical machinery, and chemical industry.
Raw tape is a novel and ideal sealing material. Because of its non-toxic, odorless, excellent sealing, insulation and corrosion resistance, it is widely used in water treatment, natural gas, chemical industry, plastics, electronic engineering and other fields.
