1)Flexible graphite roll is made by flake graphite with high carbon content, which is gone through chemical treatment, expanding under high temperature and then rolling.
2)Flexible graphite roll or sheet has the characteristics of high temperature resistance, corrosion resistance and good elasticity.
3)Flexible graphite roll or sheet sevrve as the basic material for making all kinds of reinforced graphite sheets, graphite tapes, packing and sealing gaskets. Working temperature-200~650ºC(in air),-200~3000ºC(in non-oxidizing media).
