Flexible
graphite roll (sheet) is made from flake graphite with
high carbon content which is gone through chemical treatment,
expanding under high temperature and then rolling.It has the
characteristics of high temperature resistance, corrosion resistance
and good elasticity, and 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). |
