Graphite Foil
Graphite Foil is a highly reflective, flexible graphite sheet material. It is used as a sealing material for high temperature, high-pressure transfer of steam, water, gases, chemicals and corrosives, usually in the form of a gasket. Graphite foil can also be used as a thermal barrier at extremely high temperatures providing excellent reflectivity as well as a physical barrier which will help prevent infiltration of various process gasses.
