Barite also called barium sulfate is white powder, the relative density is 4.0-4.6, good whiteness,good dispersibility, is non -toxic,tasteless,resist acid, alkali and organic solvent.
these materials donot react with any gas. so it has heat resisting and weather fastness, corrosion resisting property.
it is the best choice of outdoor product
