IG004-01 expanded graphite sheet
Flexible Graphite Homogeneous Sheets
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, As gasket material, it is usually fabricated into Graphite Laminate, and widely used in fluid sealing applications: flange gasket, spiral wound gasket, heat exchanger gasket, etc. It can also be used as solid lubricant in metal stamping and forming applications, or as heat liner in industrial furnaces and other heating devices.
working temperature -200~650 ℃(in air),-200~3000℃( in non-oxidizing media)
