Flexible graphite products is a new kind of world is resistant to high temperature, high pressure and resistance to chemical corrosion of advanced sealing material, it is made of natural flake graphite with special chemical physical treatment, it besides has the excellent properties of the original natural graphite, also increased the good flexibility and resilience, to better adapt to the request of the seal and abrasion resistance structure engineering. In the oxidation medium, can the temperature 200-2900 ℃.
