Expandable Graphite   The expandable graphite manufactured 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. When the expandable graphite was treated in a twinkling at high temperature, the form of flake has turned into that of worm, and it can expand from 100 to 400 times. This expandable graphite still remains the characteristics of natural graphite, and also has good plasticity, extrusion and excellent sealing. It is a super raw material of all kinds of graphite sheet and sealing products. It is also used in metallurgy as protective slag and heating agent.
