It is made of high-carbon flake graphite by chemical treatment and high temperature expansion and rolling, which has the characteristics of high temperature resistance, corrosion resistance, and full of elasticity.
At the same time, using this as raw material, our company produces graphite reinforced composite plates, metal wound gaskets, flexible graphite packing rings, and flexible graphite reinforced composite gaskets.
