Sealon sheet gasketing is made of 100% expanded P.T.F.E. by using special process that produces a uniform and highly fibrillated microstructure with a great lot of fibers running in multidirection. These create a soft and pliable, yet very tough gasket that has excellent resistance of pressing, creep relaxation and cold flow. It can seal the uneven and damaged flanges. Sealon sheet gasketing possesses universal resistance against common chemicals, except melted alkali metal, fluorine at liquid and gas states. It is free from asbestos and other lung-intruding materials. It meets the FDA requirements, doesn't have any corrosion and is able to be stored without any time limits. 100% expanded PTFE Gasket, manufactured through the Isometric expansion process which provides a highly fibrillated microstructure with nearly equal tensile strength in every direction. This unique structure maximizes performance predictability and stability while minimizing creep and cold flow. This Gasket definitely is an all purpose gasket sheet that is setting new standards in gasket technology. Our PTFE Gaskets are very soft and extremely compressible with relatively light torque, It can be applied in FRP, porcelain, plastic and glass-lined piping or vessels. Yet this material is very strong and tough. It can withstand compressive loads of over 40,000 PSI without affecting its sealing capability. This Gasket is the one virtually impossible to abuse.
