Product Introduction
Precipitated Barium Sulfate is a white powdery inorganic chemical product refined through chemical precipitation process. It features high purity, good whiteness, uniform particle size and stable chemical properties. It is acid and alkali resistant, corrosion resistant, insoluble in water and organic solvents, with excellent dispersion and fluidity. It is a high-quality functional filler widely used in coatings, plastics, rubber, inks and other industries.
Product Features
