Product Description
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 panicle size. The bulk density of the yvorm-like graphite powders is about 0.003G/cc. Then they are formed into graphite sheets by rolling.
Principal applications:
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.
