Precipitated barium sulfate is an inorganic substance having the chemical formula BaSO4. It is a white, crystalline material that is odourless and insoluble in water. The white opaque look and great density are used in its primary applications. Precipitated barium sulfate is widely used in industries such as powder coating, paint coating, paper, plastic, and rubber due to its purity, low oil absorption, high burning point, insolubility in water, accurate PH value, prolonged shelf life, non-toxicity, and efficacy.

Precipitated barium sulfate is a synthetic barium sulfate precipitated at a specific particle size.These products work well with industrial paints, enamels, and plastic materials. Also known as blanc fixe, this high purity, synthetically generated barium sulphate substance is used as an extender in the creation of paints, coatings, and polymers. It is entirely harmless and extremely resistant to outdoor exposure and other pollutants. The precipitated barium sulphate has a tiny particle size of 0.7 µm and a narrow distribution of particle sizes, making it perfect for high gloss applications.

High Purity

Precipitated barium sulfate is normally highly purified, ensuring that it meets demanding quality criteria for a wide range of industrial uses. High purity is required to reduce contaminants that could impair the performance of the finished product.

Whiteness

One of the distinguishing features of precipitated barium sulfate is its high level of whiteness. This feature makes it ideal for use in applications requiring bright and colorful colors, such as paints, coatings, polymers, and cosmetics.

Light Resistant

Precipitated barium sulfate has good resistance to light degradation. This feature guarantees that items containing barium sulfate retain their colour and appearance after long periods of exposure to sunshine or artificial light sources.

Weather Resistant

Precipitated barium sulfate is extremely resistant to weathering impacts, including exposure to outside elements such as rain, wind, and temperature variations. This resistance contributes to the integrity and performance of outdoor products such as paints and coatings for building exteriors.

Use of Precipitated barium sulfate in Paint and Coatings Industry:

Precipitated barium sulfate is used as a pigment extender in paints and coatings to increase opacity and whiteness. It improves the paint's hiding power, allowing for more coverage of the substrate. Because barium sulfate is chemically inert, it can be used in paints and coatings that require chemical resistance and long-term disintegration. It improves the weather resistance of paint formulas, ensuring that the coating retains its color and appearance even when exposed to adverse climatic conditions.

Use of Precipitated barium sulfate in Plastics Industry:

Precipitated barium sulfate is used as a filler in plastic formulations to improve mechanical qualities such as stiffness, impact resistance, and dimensional stability. It enables precise control over the density of plastic items, making it ideal for applications where weight is an important consideration, such as automotive parts and packaging materials.Barium sulfate can also improve the flame retardancy of polymeric compounds, making them appropriate for use in applications where fire safety is a concern.

Use of Precipitated barium sulfate in Rubber Industry:

Precipitated barium sulfate is used as a reinforcing filler in rubber compounds to increase mechanical qualities like tensile strength, tear resistance, and abrasion resistance. Barium sulfate reduces the overall cost of rubber formulations by partially replacing more expensive reinforcing ingredients such as carbon black or silica. It increases the processability of rubber compounds during mixing, extrusion, and molding, resulting in better filler dispersion and homogeneity in the finished rubber products.

Use of Precipitated barium sulfate in Adhesive Industry:

Barium sulfate is used in adhesive compositions to improve mechanical qualities including tensile strength and stickiness. It can be used as a thickening agent in adhesives to manage viscosity and improve formulation stability. Barium sulfate improves adhesives' chemical resistance, ensuring that the bond remains strong even when exposed to severe chemicals or environmental conditions.
