Details
Barium sulfate, also known as blanc fixe, is a high-purity, chemical compound with the formula BaSO4. It is widely used in the industrial sector as a weighting agent, filler, and coating material due to its excellent chemical and physical properties.
Barium sulfate is a white, odorless, and tasteless powder that is insoluble in water and other common solvents. It has a high melting point of 1580°C, making it resistant to thermal decomposition. Its high density of 4.5 g/cm³ and low oil absorption make it ideal for use in the production of paints, coatings, and plastics.
In the oil and gas industry, barium sulfate is used as a weighting agent in drilling muds to control formation pressures and prevent blowouts. It is also used in medical imaging procedures such as X-rays and CT scans due to its high radiopacity.
At our company, we offer high-quality barium sulfate that meets industry standards and regulatory requirements. Our product is available in various grades and packaging options to meet the diverse needs of our customers.
We pride ourselves on our commitment to providing exceptional customer service and technical support to help our clients achieve their goals. Contact us today to learn more about our barium sulfate products and how they can benefit your business.

Application area
Coatings and paints
Powder coatings: especially suitable for thin coating systems with high gloss requirements, Particle Fine Micro can partially replace other pigments and significantly reduce volatile compounds (VOC).
Automotive paints: Good light retention and excellent mechanical properties, especially suitable for high gloss systems.
Pigment paste: Particle Fine Micro is used as a pigment incremental dispersant to improve the dispersion of pigment powder, which can effectively improve the color vividness and brightness. At the same time, it can reduce the coagulation or flocculation of pigments and make the storage more stable, and replace 10-20% of the total pigments in the formula, the gloss of the formula will not be reduced.
Inks
General ink: Not only improves the gloss of the ink, but also has excellent fluidity.
Line board ink: Cost reduction, smooth and round paint film, good gloss and good whiteness.
Rubber and Plastic
Thermoplastics: Improves the rigidity, hardness and wear resistance of plastic products. particle Fine Micro has high thermal conductivity and rheological properties that shorten the cycle time of injection molding. It also increases the crystallinity of thermoplastic polymers, thus improving the strength (especially impact strength at low temperatures) and stability of products.
Elastomers : Free of rubber toxins, especially suitable as fillers. Has storage stability and anti-aging properties.
Masterbatch ：Improve the efficiency of using color powder in masterbatch and slurry, presenting texture and luxury. Play the role of pigment dispersant in masterbatches.
Others
Films: In stretch and ductile films, it can be used as white pigment and reduce cost by reflecting visible light at the interface between Particle Fine Micro, air two phases.
Children's toys: Particle Fine Micro meets FDA requirements, plus its X-ray opaqueness can be used in children's toy applications. (Easy to find after accidental swallowing)
Packaging and storage
25Kg/pack, 1000Kg/pallet.
Keep the package closed and unopened, and keep it in a dry room at room temperature, we recommend to use it within 12 months from the date of shipment for better results.
