Description :

Barium Sulphate Supplier and Exporter for the USA

Chemical Bull supports commercial sourcing as a Barium Sulphate supplier, distributor, wholesaler, and exporter for the USA, serving paint manufacturers, coating formulators, plastic compounders, drilling-fluid businesses, and industrial procurement teams.

Barium Sulphate, commonly spelled Barium Sulfate in the United States, has CAS No. 7727-43-7. It is an inorganic material used as a mineral filler, pigment extender, and weighting material. Buyers should review grade, purity, particle size, whiteness, specific gravity, COA, SDS, and batch consistency.

Quick Answer

Barium Sulphate is an inorganic compound with the formula BaSO₄. Industrial uses include paints, coatings, plastics, and suitable drilling-fluid weighting applications. USA buyers should distinguish natural barite from precipitated grades and specify particle size, purity, quantity, packaging, documentation, and delivery destination when requesting bulk pricing.

What Is Barium Sulphate?

Barium Sulphate is a dense inorganic compound with very low solubility in water. It occurs naturally as the mineral barite and is also produced through chemical precipitation.

The Barium Sulphate formula is BaSO₄, representing barium ions combined with sulfate ions.

Natural and precipitated grades can differ in purity, particle distribution, whiteness, and other performance characteristics. Precipitated Barium Sulphate is commonly called blanc fixe. Buyers should select the material according to the intended application.

Barium Sulphate Uses in Industrial Manufacturing

Paints and Coatings

Barium Sulphate is used as a filler and extender in selected paint and coating formulations.

Formulators should evaluate particle size, whiteness, oil absorption, dispersion, and compatibility with the binder system to achieve the required finish and processing behavior.

Powder Coatings

Suitable Barium Sulfate grades are used in powder coating formulations, including selected matte and semi-matte systems.

Manufacturers should qualify particle distribution, moisture, processing behavior, surface appearance, and finished-film performance against the approved formulation.

Plastics and Polymer Compounding

Barium Sulphate is used as a mineral filler in selected plastic and polymer compounds.

Its high density can support applications requiring increased material weight. Compounders should evaluate dispersion, polymer compatibility, loading level, and mechanical properties.

Drilling-Fluid Weighting

Suitable natural barite grades are used as weighting materials in drilling fluids.

Drilling-fluid buyers should confirm specific gravity, particle-size distribution, relevant impurity limits, and applicable technical specifications. A coating-grade product should not automatically be treated as drilling-grade material.

Adhesives and Mastics

Selected Barium Sulphate grades are used as fillers in adhesive and mastic formulations.

Formulators should assess viscosity, settling behavior, dispersion, density, and finished-product performance before commercial approval.

Why Manufacturers Source Barium Sulphate

High-Density Mineral Function

Barium Sulphate supports qualified formulations requiring a dense filler or weighting material.

Low Water Solubility

Its very low water solubility makes it useful in selected industrial filler applications.

Application-Specific Grade Selection

Defined particle size, purity, whiteness, and specific gravity help buyers match the material to their production requirements.

Bulk and Repeat Procurement

Recurring purchases can be planned around approved specifications, batch documentation, packaging, and production schedules.

Barium Sulfate Supplier for USA Manufacturers

When comparing Barium Sulfate suppliers for the USA, procurement teams should confirm whether the material is natural or precipitated and review assay, particle-size distribution, moisture, whiteness, specific gravity, and relevant impurities.

Coating and polymer buyers may also require oil absorption, dispersion, or surface-treatment information. Drilling-fluid buyers should request documentation supporting the required drilling-grade specification.

Chemical Bull accepts commercial enquiries from manufacturers, formulators, distributors, and bulk buyers across the United States. Confirm available grade, packaging options, minimum order quantity, lead time, and delivery feasibility before ordering.

Related Mineral Fillers and Pigments

Manufacturers sourcing Barium Sulphate may also explore Calcium Carbonate, Titanium Dioxide, and Mica.

These materials differ in density, particle characteristics, optical properties, and formulation function. Select each according to the intended application.
