The expanded PTFE belt is a very novel and unique sealing material made by a unique processing technology. It is made of 100% expanded polytetrafluoroethylene (EPTFE) material and self-adhesive on the back. It is easy to use. The material has unique properties and can be pressed into a thin and wide strip. It is suitable for various types. Regular surface. It has good flexibility, compression resilience, creep resistance, high and low temperature resistance, excellent corrosion resistance, non-aging properties and self-lubricating properties. Excellent sealing performance, extremely convenient installation and use, it is an ideal sealing material for chemical, pharmaceutical, petrochemical, food and beverage, electronics, electric power, metallurgy, shipbuilding and other industries.
High temperature resistance - use working temperature up to 310 °C.
Low temperature resistance - good mechanical toughness; 5% elongation even at temperatures down to -196 °C.
Corrosion resistance - It is inert to most chemicals and solvents, resistant to strong acids and alkalis, water and various organic solvents.
Weather resistant - the best aging life in plastics. Highly lubricated – the lowest coefficient of friction in solid materials.
Non-adhesive - is the smallest surface tension in solid materials and does not adhere to any substance.
