MAGNESIUM CARBONATE

Our magnesium carbonate is a product of basic magnesium carbonate manufactured by the seawater process developed with our
original technology, and the product are white and fine crystal having chemical composition 4MgCO3.Mg(OH)2.4H2O

GOLD STAR show excellent light transparency in case of blending with rubber.
Heavy type Magnesium carbonate has larger bulk density and less impurities than ordinary products.

Magnesium Carbonate Granular is granular type, so it shows good workability and improves productivity.
