Duratight graphite foil roll can be 0.127~1.600mm thick.
graphite foil , graphite roll has high content of carbon, meanwhile 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 ,stuffings, and sealing gaskets.
Working temperature:-200 to 650 degrees centigrade(in the air) ; -200 to 3000 degrees centigrade( in Non- oxidation Medium)
