  > Others Series >> EXPANDED GRAPHITE ROLLING (SHEETS)


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