Graphite gasket sheets are sealing sheets made from flexible graphite which provides a soft, highly adaptable surface.
The sheets can be unreinforced i. e. homogeneous and made from flexible graphite only or reinforced resulting in a multilayer sheet, which is sometimes also referred to as a graphite laminate. Common reinforcements are flat or tanged stainless steel, other metals like nickel or nickel alloys, and polyester film.
The sheets are further processed into flat gaskets of different shapes by
punching or cutting. Graphite soft cut gaskets are ideal for many applications due to their wide operating temperature range (-269 °C to max. 550 °C) and excellent media and corrosion resistance.
The portfolio of SIGRAFLEX graphite sheets made from flexible graphite provides a variety of solutions to all needs. We offer gasket sheets for flat gaskets in different variants e.g. unreinforced or reinforced, with or without impregnation, with adhesives or binders as well as adhesive-free. SIGRAFLEX graphite gasket sheets are manufactured exclusively at our two sites in Germany and the US.
