Expanded PTFE belt
Expanded PTFE belt Penguin PN5200
PN5200 expanded PTFE sealing tape, also known as expanded PTFE interface belt, is a universal gasket that can be safely and effectively used in various corrosion-resistant and high-purity applications such as plastics, stainless steel, enamel and other flanges. It is a continuous strip of 100% PTFE white pure PTFE product, without any filler, and has high safety. Its microcellular structure has lower compressive creep and cold flow properties than other tetrafluoro articles. Its flexibility, compression resilience, creep resistance, high and low temperature resistance, excellent corrosion resistance, non-aging, self-lubricating properties make it excellent in sealing performance. It comes with adhesive and can be made on site. The gasket of any shape can be easily installed without prior preparation. Compared with ordinary stamping gaskets, it saves lead 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.

1, a variety of enamel lining, glass lining, plastic lining, graphite lining and stainless steel, titanium steel towers, heat exchangers, reactors and other flange surface sealing.
2. Flange surface sealing of various pipes and pipe fittings.
3, the surface processing accuracy is poor, the uneven area is large, the shape is irregular, the bolt fastening force is not easy to use the flange surface seal of the large diameter equipment that is not enough or not too large.
4. Strongly corrosive media and seals of fluids that cannot be contaminated.
