An expanded graphite based material that has excellent chemical and thermal resistance. Its high creep resistance and high compressibility make it suitable for highly demanding conditions in the chemical and petrochemical industries, gas supply, compressors and pumps.

Plain graphite sheet can be used for flange gasket in relatively low pressure sealing condition. Attributing to good thermal conductivity of graphite, it is an ideal filler material for metal jacketed gaskets (corrugated metal gaskets, heat exchanger gaskets).
