We are utilizing non-metal oxidant and electrochemical method to reduce the contents of chloride, fluorine and heavy metal. This makes it possible for our manufacture to meet different clients' special requirements, i.e low sulphur, anti oxidation, low temperature resistant, etc.
The grades of expandable graphite are identified by particle size.
As per particle size: 32mesh, 80 mesh, 50 mesh, 100mesh
