Grafoil Gasket Material

Grafoil Gasketing

GRAFOILflexible graphite was one of the first fluid sealing material made exclusively from pure, natural graphite flake.  Its resistance to heat, fire, corrosion and aggressive chemicals make it one of the most universally applicable sealing solution in the market today.  Like no other, GRAFOIL products provide a very tight seal after repeated exposure to the harshest environments.

GTB:
Grafoil homogeneous. Standard Industrial Grade flexible graphite sheet with an oxidation/corrosion inhibitor and typically 98% carbon content. Its leachable Chloride content is less than 50 ppm. It is an ideal facing material for flat gaskets It contains no binders or resins. No binders or resins. Non-fibrous. Non-asbestos. Sulphur content <500 ppm. Compressibility: 43%. Recovery: 15%. Creep relaxation: <5%. Tensile strength: 650 PSI. 
Temperature range (oxidizing atmosphere): -400°F to 850°F. (Properties based on 1/16” thickness.)
