Expanded PTFE Expanded PTFE sealing tape sealing tape is made by a special process of pure PTFE products, with good flexibility, compression elasticity, creep resistance, high temperature resistance and excellent corrosion resistance resistance, aging resistance, self lubrication. Sealing performance, installation extremely easy to use, chemical, pharmaceutical, petrochemical, food and beverage, electronics, electric power, metallurgy, shipbuilding and other industries very ideal sealing material sealing tape uses: Expanded PTFE sealing tape for a variety of enamel lining , glass-lined, plastic lining, rubber lining, graphite lining and stainless steel, titanium and steel towers, heat exchangers, reactors, etc. flange seal. Variety of pipes and pipe fittings flange seal. Surface machining accuracy is poor, uneven area is large, irregular shape, bolt tightening force should not be too difficult to use large enough or large-diameter flange face seal device. Strong corrosive medium and the slightest contamination can not be fluid-tight seal.
