316 S.S. Foil Inserted  Flexible Graphite

Flexible graphite sheet laminate with tang 316 stainless steel insert (0.005 thick) made from material typically 98% graphite. Leachable chloride typically less than 50   ppm. Sulfur content: 1200 ppm. Compressibility: 35%. Recovery: 18%. Creep relaxation: 10%. Density: 62.4 lbs/ft. Tensile strength: 5000 PSI. Temperature range (oxidizing atmosphere): -400 F to 750 F

Flexible Graphite - Seals like no other sealing material. Flexible graphite will handle higher temperatures than any elastomeric of non-asbestos gasketing and handle a ph range from 0-14.

Developed originally by Union Carbide under the brand name "Grafoil".  Flexible graphite solves industries difficult sealing applications.
