316 S.S. Foil Inserted Flexible graphite sheet
It is made from flake graphite with high carbon content ,made by chemical treatment, expanding under high temperature and then rolling.It has the characteristics of high temperature resistance, corrosion resistance and good elasticity, and it is 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)
