oxidation resistance felxible graphite sheet only lose 4% of its weight at 670A°c/h

タイトルまたは説明

 Flexible graphite sheet&roll, is made from flake graphite with high carbon content which is gone through chenmical treatment ,expanding under high temperture and then rolling,it has the characterisitcs of high temperture resistance,corrosion resistance and good elasticity,and is the basic material for making all kind of reinforced graphite sheets,graphite tapes,packing and sealing gaskets  

 ~ Standard of Oxidation graphite
