Application of Barium Sulfate in the Industry
Coatings/ paints/ inks industry
Barium sulfate, as a high-quality physical pigment and functional filler, has stable chemical properties, low oil absorption, and good dispersibility. In coatings and paints, it can improve the hardness, glossiness, and weather resistance of the paint film, effectively reduce raw material costs, and is suitable for categories such as architectural paint, industrial paint, powder paint, and anti-corrosion paint; When applied to ink, it can adjust the viscosity and leveling of the ink, making the printing layer smooth, full, and uniform in color. It is widely suitable for various printing inks such as offset printing, gravure printing, water-based printing, and screen printing.
Pharmaceutical industry
Pharmaceutical grade barium sulfate has stable chemical properties, is non-toxic and harmless, and has strong ability to block radiation, making it an important raw material in the pharmaceutical field. Mainly used as a gastrointestinal contrast agent, it is not absorbed by the human body after oral administration and can be clearly visualized under X-rays to assist in the examination of lesions in the esophagus, stomach, intestines, and other areas; It can also be used as a medicinal excipient, added to ointments and topical preparations as a filler and rheology regulator to enhance the stability and texture of the ointment. It is widely used in medical imaging examinations and the production of various topical drugs.
Glass/ Ceramic Industry
Barium sulfate has stable chemical properties, high temperature resistance, and excellent whiteness, making it a commonly used functional raw material in the production of glass and ceramics. Added to glass, it can enhance the whiteness, luster, and translucency of the product, optimize the melting state, and is commonly used in optical glass, decorative glass, and process glass; Applied in ceramics and enamel glazes, it can increase the smoothness and density of the glaze surface, reduce pinhole and bubble defects, brighten the color, and stabilize the glaze layer. It is suitable for daily ceramics, architectural ceramics, enamel products and other categories.
Plastic industry
Barium sulfate is a commonly used functional filler in the plastic industry, with strong chemical stability and excellent glossiness. After addition, it can improve the surface smoothness, hardness, and dimensional stability of plastic products, with shading and noise reduction effects, while reducing production costs. It is widely used in various rubber and plastic products such as plastic particles, profiles, pipes, films, household appliance shells, and plastic masterbatch.
