Natural graphite flake is chemically treated to form Graphite
Intercalation Compound. This intercalation compound is then rapidly heated to decomposition. The result is a rapid expansion of the particle size. The bulk density of the worm-like graphite powders is about 0.003g/cc. Then they are formed into graphite sheets by rolling.

Principal applications:
a??a??a??a??A��Glands
a??a??a??a??A��Gaskets used in flanges, covers of observation holes, level meters.
a??a??a??a??A��Direct attach to the metal surfaces for gas phase sealing effectively.
a??a??a??a??A��Especially the expanded graphite rolls can be used as a material for
a??a??a??a?? automatic producing lines.
