we adopt non metal intercalant through chemical or electrochemical method to manufacture gra-eg to avoid the contents of chlorine, fluorine, bromine and heavy metal compounds.
gra-eg is also processed without lead and chromium. It eliminates the need and expense to dipose of hazardous waste.
the surface chemistry of gra-eg can be adjusted to meet specific processing or formulation requirements.
our process makes it possible to meet the specific requirements of different customer, such as low sulphur, anti oxidation, onset temperature adjustable, etc.
particle size available: 32 mesh, 50 mesh, 80 mesh, 100mesh
