The product is made from flake graphite with high carbon content which is gone through chemical treatment, expanding under high temperature and then formed by rolling. It owns the characteristics of high temperature resistance, corrosion resistance and good elasticity. Flexible graphite sheet or roll is the main raw material for making all kinds of graphite tapes, reinforced graphite sheets, sealing and packing gaskets, etc.
