PTFE sealing tape PTFE sealing belt

Expanded ptfe sealing belt, also known as expanded PTFE interface belt, is a versatile gasket for safe and effective use in a variety of plastic and stainless steel, enamel flanges in high corrosion and high purity applications. It is a continuous band of 100%PTFE white pure PTFE products, without any filler, with a high safety. Its microcellular structure has lower compressive creep and cold flow properties than other ptfe products. It has flexibility, compression resilience, creep resistance, high and low temperature resistance and excellent corrosion resistance, non-aging, self-lubrication makes the sealing performance is excellent, it comes with the back glue, can be made into any shape of gasket on the spot, without prior preparation, use and installation is very convenient. Compared with ordinary stamping gasket, it saves delivery time and corner cost. It is an ideal sealing material for chemical, pharmaceutical, petrochemical, food and beverage, electronics, electric power, metallurgy, shipbuilding and other industries.

Performance characteristics:
· High chemical resistance
· Honeycomb pure PTFE, compound FDA requirements
· Low creep and cold flow performance
· Easy installation shortens maintenance time and reduces cost

Applicable medium: all chemical substances except elemental fluorine and molten alkali metal.
Application scope:
· Seal flange surfaces of various enamel linings, glass linings, plastic linings, graphite linings and stainless steel, titanium steel towers, heat exchangers, reaction kettle and so on.
· Flange face sealing of various pipes and pipe fittings.
· Poor surface processing accuracy, large uneven area, irregular shape, bolt fastening force is not easy to use enough or not too large diameter equipment flange seal.
· Sealing of highly corrosive media and fluids that cannot be contaminated at all.
