Flexible Graphite Sheet & Rolls
Material Description

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).
