Graphite Gaskets

The Graphite range of sheet sealing materials is manufactured from high purity exfoliated graphite flake, and is available with or without a reinforcing metallic core. The “standard” product range is based upon graphite with a minimum carbon content of 98% and, for nuclear applications graphite with a minimum carbon content of 99.85% is available. The graphite foils can be attached to the reinforcing core by mechanical means or by the use of selected adhesives. Graphite laminates are particularly suited for applications involving moderately high temperatures and pressures in a wide range of media. They are widely used in demanding industrial applications and in the petrochemical/refining industries. Because these products do not contain any rubber or polymeric binders they have the highest levels of stress retention, ensuring that gasket stress applied during assembly is maintained during service. Graphite based products are resistant to most industrial chemicals but susceptible to attack by oxidizing agents such as nitric acid. Sulphuric acid can also attack graphite at certain combinations of concentration and temperature. When selecting a graphite laminate for use in chemical service, consideration must be given to any possible reaction between the chemical medium and the reinforcing metallic core.
