Product description: Graphite sheet reinforced with metal foil is made from there layers, at the middle of the flexible graphite sheet is one stainless steel foil. Through specially pressing or sticking process. The insert materials can be SS304, SS316, Nickel, etc. It can be used in the condition of high temperature, high pressure and sealing.
Flexible Graphite Sheet, normally we call it "Expanded Graphite Sheet", it is made from high quality and purity flake graphite, which is gone through chemical treatment, expanding under high temperature and then rolling. It is a basic material for making different kinds of graphite sealing products.
