The flexible graphite sheet & flexible graphite rolls offered by us are manufactured using flake graphite with high carbon content. These flakes are chemically treated, expanded under high temperature and then rolled. These are appreciated for features such as high temperature resistance, corrosion resistance and good elasticity. Our Sheets and Rolls are the basic material for manufacturing reinforced graphite sheets, graphite tapes, packing and sealing gaskets.
