In many applications, these materials are expected not only to be resistant to corrosion, high temperatures, and high pressures, but also to provide elastic compensation, prevent brittle material failure, ensure safety and stability, and have a long service life – all of which place very high demands on the sealing materials used. High-performance expanded polytetrafluoroethylene can solve this technical challenge that has remained insurmountable for many years in industries such as chemicals and petrochemicals. As a new type of sealing material, Fle*ngSeal® offers new solutions to problems such as leaks, spills, and other forms of fluid loss in chemical processing equipment. Due to its light weight, high strength, and unchanged properties at ultra-low temperatures. Various sealing components made from expanded polytetrafluoroethylene are the most widely used sealing materials in today’s world, across industries such as chemicals, petrochemicals, oil, biochemistry, aerospace, pharmaceuticals, food, and beverages. It opened up new horizons in the field of modern industry. The specific application areas are as follows: (1) Sealing of large-diameter containers: containers, towers, reactors, heat exchangers, evaporators, etc ； (2) Sealing of various fragile surfaces such as enamel, glass, and plastic ； (3) Poor surface finishing accuracy or damage to the sealing surface leads to leakage ； (4) Sealing for strong acids and bases, and highly corrosive media ； (5) Sealing in environments with high cleanliness requirements: Sealing in industries such as food, beverages, pharmaceuticals, and biochemistry ；
