China is the big country producing graphite, output and export quantum occupy the first place in the world. In order to meet market developments needs, the carbon chemical compound research institute was established in 1998, according to the customers different demands organize a large amount of scientific research strength, develop the low-sulful Expandable Graphite and Ultrafine Expandable Graphite. Every technical indicator belongs to the international leading level. The expandable graphite manufactured by our company is a flexible graphite product with professional treatment on the high quality natural flake graphite. It is a very ideal and new type sealing material, widely used in dynamic and static seals in petroleum, chemical industry, electricity, astronomy, automobile, ship and other apparatus. We are full of confidence even if we face European and American enterprises with advanced technology.
