Barium Sulfate (or Sulphate) is the inorganic compound with the chemical formula BaSO4. It is a white crystalline solid that is odorless and insoluble in water. It occurs as the mineral barite, which is the main commercial source of barium and materials. The white opaque appearance and its high density are exploited in its main applications.
Plastics: Excellent hiding power. Outstanding mechanical characteristics and wears resistance. Non qualitative white powder. Non toxic, not soluble in water, soluble in smoking sulfuric Acid, slightly soluble in boiling hydrochloric Acid. Chemical property is stable, it'll reduce to Barium Sulfide when heat with carbon. As a stable chemical filler, it can enhance the strength, weatherability and gloss of plastic products.
Barium sulfate is commonly used as a filler for plastics to increase the density of the polymer in vibrational mass damping applications. It has an effect of increasing acid and alkali resistance and opacity. Such composites are also used as X-ray shielding materials due to their enhanced radiopacity. Composites with high mass fraction (70–80%) of barium sulfate perform better than commonly used steel shields.
Factory standard: 25kg/bag, plastic woven bag with lining.
