flexible graphite roll,expanded graphite roll/sheet

1)graphite roll is made by high purity graphite; 2)lowest thickness in 0.15mm up to 5mm 3)C more than99;S less than1200ppm

1)Flexible graphite roll is made by flake graphite with high carbon content, which is gone through chemical treatment, expanding under high temperature and then rolling.

2)Flexible graphite sheet  has the characteristics of high temperature resistance, corrosion resistance and good elasticity.

3)Flexible graphite sheet sevrve as  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).
