Abstract: Partially expanded graphite flake having a specific volume of no more than about 50 cm3/g, more preferably, about 10-25 cm3/g has excellent sheet forming properties and is readily moldable to form molded products, such as gaskets. The partially expanded graphite flake may be produced by a low temperature process, in which the flakes are first intercalated with an intercalation solution, then subjected to a low temperature exfoliation of below about 500° C. In an alternative process, the flakes are intercalated with no more than about 40 pph of an intercalation solution (less if the particles are not subjected to a subsequent washing step) and then exfoliated at conventional exfoliation temperatures of about 800° C.
