Flexible graphite sheet(Roll) is made from flake graphite with high carbon content which is gone through chemical treatment,expanding under high temperature and them rolling,it has the characteristics of high temperature resistance,anti-irradiation,low creep relaxation and good elasticity,and it is the basic material for making all kinds of reinforced graphite composite sheets;graphite tapes;gland packing and sealing gaskets,working temperature -200~650 ℃(in air),-200~3000℃( in non-oxidizing media)
