GF-I Flexible Graphite Sheet

GF-I flexible graphite sheet for industry sealing applications

Flexible Graphite Sheet

Flexible graphite sheet is made of pure expanded natural graphite. GF-I as our standard flexible graphite sheet product has a high purity of  99.0% carbon content. Higher carbon content gives the flexible graphite foil better chemical resistance, better thermal conductivity, and better sealing ability.

GF-I our standard flexible graphite sheet suitable for most industry applications. As gasket material, it is usually fabricated into Graphite Laminate, reinforced graphite sheet 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 industry furnaces and other heating devices.
