Home - Precipitated Barium Sulphate Product Portfolio | RBH Ltd Precipitated Barium Sulphate High purity precipitated barium sulphate grades from the SintaBar range, delivering exceptional whiteness, controlled particle morphology, low oil absorption, and reliable dispersion performance across coatings, inks, thermoplastics, adhesives, sealants, and speciality industrial applications. CAS NUMBER: 7727-43-7 Request A Sample Names Precipitated Barium Sulphate | Precipitated Barium Sulfate | Precipitated Baryte | High Purity Barium Sulphate Chemical formula BaSO₄ Product Overview SintaBar is RBH Group’s range of high purity precipitated barium sulphate grades developed for applications requiring exceptional whiteness, controlled particle morphology, and outstanding formulation consistency. Produced through a carefully controlled precipitation process, SintaBar offers a finer and brighter alternative to conventional natural barytes grades, supporting enhanced optical performance, improved surface finish, and excellent dispersion characteristics across demanding industrial systems. The range is designed for use where colour stability, gloss control, low oil absorption, and formulation cleanliness are essential. Carefully controlled particle size distribution supports smooth incorporation and consistent processing behaviour across coatings, inks, plastics, adhesives, sealants, and speciality industrial applications. SintaBar is widely used within decorative and industrial coatings, powder coatings, printing inks, transparent and semi-transparent systems, engineering thermoplastics, elastomers, and speciality compounds where high purity and long-term performance are critical. Its chemically inert nature and excellent weather resistance make the range particularly suitable for demanding environments requiring durability, colour retention, and formulation stability.
