Abstract
A process for the production of flexible graphite comprising incorporating particulate expanded graphite having a c direction expansion at least 10 times as great as that of the original c direction dimension with an organo-silicon high molecular weight compound having carbon and silicon as the skeletal components, such as polysilmethylenesiloxane, or with a colloidal silica, drying the resulting mixture, pressure molding the dried mixture and heat treating the molded mixture at 500.degree.-2000.degree. C. thereby to produce the flexible graphite. In one embodiment, this invention relates to flexible graphite obtained by the process.
