Flexible graphite is manufactured from mineral graphite (expandable flake graphite). It is also called graphite foil, or referred to by a brand name such as Grafoil®. As its name indicates, flexible graphite is flexible and conformable, an ideal property as a gasket material. Flexible graphite can also be used in many other thermal, electronic or electrochemical applications.
