Flexible Graphite Roll,Expanded Graphite Roll Sheet , Find Complete Details about Flexible Graphite Roll,Expanded Graphite Roll Sheet,Graphite Roll,Graphite Roll,Graphite Roll from Graphite Sheets Supplier or Manufacturer-Changyi Dongfeng Sealing Materials Co., Ltd.
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 sheet has the characteristics of high temperature resistance, corrosion resistance and good elasticity.
3)Flexible graphite 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).
