High-Purity Barium Sulfate for Premium Fillers & Extenders
Barium Sulfate is a non-toxic, odorless, and non-corrosive white inorganic compound with the chemical formula BaSO₄. It primarily exists as the natural mineral barite but can also be synthetically produced (known as precipitated barium sulfate). Due to its exceptional chemical stability, high whiteness, high specific gravity, and excellent optical properties, it is widely used as a functional filler and extender across various industries.
- Exceptional chemical stability and high whiteness
- High density and specific gravity
- Low oil absorption for good processability
- Excellent wear resistance and hardness
Key Product Advantages
A unique combination of density, optical performance, and chemical stability in a single filler.
High Density & Specific Gravity
Its high specific gravity makes it ideal for applications requiring weight, sound damping, or radiation shielding.
Excellent Optical Properties
High whiteness and refractive index enhance film opacity, gloss, and surface smoothness.
Low Oil Absorption
Low oil absorption allows high loading levels with good processability and reduced resin demand.
Wear Resistance & Hardness
Improves the hardness, abrasion resistance, and durability of coatings and molded parts.
Where Barium Sulfate Is Used
A premium functional filler across coatings, plastics, rubber, friction materials, and more.
Paints & Inks
Used as a filler to increase film thickness, hardness, abrasion resistance, and gloss. Especially suitable for high-gloss paints, primers, marine paints, and powder coatings.
Plastics Industry
Used in PP, PA, and PVC to increase product density, stiffness, surface gloss, and anti-warping properties, with good processability from low oil absorption.
Rubber Industry
Serves as a reinforcing filler in hoses, belts, and seals to enhance product density and durability.
Others
Used as a pigment (lithopone), in friction materials (brake pads), floor paints, and audio equipment (to increase weight).
