Metal graphite composite plate is enhanced by the two sides of the middle boards for the flexible graphite layer of sheet metal folder to a specific bonding process or by suppression. Flexible graphite-reinforced composite plate is an excellent sealing material, processed into a variety of high-strength gaskets primarily for piping, valves, pressure vessels manhole, hand hole flange connections, such as the static internal combustion engine cylinder seals and gaskets cylinder into the row or the basic materials. Compression of the gasket, good elasticity, stress relaxation in small, flange sealing surface roughness of the compensation ability, long service life. Applicable to acid, alkali, steam, solvents and oils, such as a variety of media.
