　Low sulfur expandable graphite produced by electrochemical method or chemical method by our company is an ideal new sealing material ， widely used for dynamic or static sealing in petrochemical industry ， chemical industry ， electricity industry ， flight industry ， automobile ， ship and instrument. This product is honored as National grade hi-tech product in 1997.
　This product uses natural flake graphite soaked with sulfuric acid solution as anode.After introduced electricity ， oxidative and reductive reactions take place between anode and cathode. The graphite intercalated chemicals formed upon thie is just the expand-able graphite.
　The properties of this product hold flexibility and elasticity ， besides normal graphitefunctions. Especially ， the major technical in-dexes such as sulfur content satisfy the major technical indexes such as sulfur content satisfy the customer. The product is mainly for export.
