Barium Sulfate Powder, 7.5μm

Catalog NumberACFR000005

CategoryFunctional Inorganic Powder

Description	Barium Sulfate Powder is a chemically stable, white, non-toxic, and non-magnetic inorganic material. It is insoluble in water, resistant to acids and alkalis, and has a high specific gravity, moderate hardness, and a high melting point of 1580°C. It effectively absorbs ultraviolet, X-ray, and gamma radiation.
Appearance	white pwder
Application	Widely used as an extender pigment and functional filler in coatings (including powder coatings and self-cleaning systems), plastics, and rubber products (such as tires and industrial belts). It is also utilized in radiation-shielding materials and as a cost-effective partial substitute for titanium dioxide in water-based paints.
BaSO₄	≥95.0%
Feature	High whiteness and uniform particle size distribution. Excellent chemical inertness, offering resistance to acids, alkalis, and heat. High specific gravity and moderate hardness contribute to durability and weight. Absorbs UV, X-ray, and gamma radiation, providing protective properties. Features low oil absorption, allowing for high filling levels and cost efficiency. Enhances thixotropy, improves leveling, and acts as an effective flatting agent. Reinforces mechanical properties like abrasion resistance, surface hardness, and impact strength.
Oil Absorption	13-16 g/100g
Particle Size	7.5±1.2μm
Volatiles	≤ 0.2%
Whiteness	≥80%
