Barium Sulfate
OVERVIEW
Cimbar Industrial Barite is the largest producer of Barium sulfate in North America. Barium sulfate is a chemically inert, high density mineral with a low surface area and is also a radiopaque agent. These characteristics make barite a perfect, high-performance filler for many applications including coatings, TiO2 extension, industrial, and X-ray contrast applications.
Cimbar supplies calcium carbonate as a fine white powder or granulation for use in industrial applications in High Bright and Off White grades.
Cimbar offers API barite options for drilling fluid applications. We are the only major producer of API barite for drilling fluid applications who is not also a drilling fluids producer.

- API barite options (drilling fluid applications). We are the only major producer of API barite for drilling fluid applications that is not also a drilling fluids producer.
- Exbar
CIMBAR’s Cimbar BF product is the next generation of precipitated extenders. With its ultra-fine particle size, high barium sulfate content, low solubility, high brightness, and chemical inertness. Cimbar BF is ideal for applications such as top coats, printing inks, powder coatings, and lead-acid batteries, and many others.
Applications for Cimbar BF
| Architectural coatings | Cosmetics | Paper |
| Automotive Primers | Gloss enamels | Plastics |
| Automotive topcoats | Gloss latexes | Powder coatings |
| Batteries | Industrial coatings | Semi-gloss latexes |
Our Cimbar Barium Sulfate grades are made using only the highest quality white, natural barium sulfate ore. The Cimbar Barium Sulfate grades unique properties of fine grind, high specific gravity, low solubility and chemical inertness make them ideal for many applications.

Cimbar’s BARA 325 grade is a more economical natural, off-white barium sulfate. Cimbar’s BARA 325 is a clean, high purity, high specific gravity, low solubility barium sulfate and it’s chemically inert. These properties have made BARA 325 the industry standard for quality and performance in a wide range of end-use applications.
Cimbar’s 4.1 and 4.2 specific gravity API barite grades for the drilling fluid market are produced from a natural barium sulfate ore and they are designed to meet or exceed all API requirements. Cimbar’s API barite grades of barium sulfate are the industry standard for quality and performance in oil field applications. Our API barite grades can also be considered for use as economical barium sulfate options for a wide range of other end-use applications that don’t require high purity and high specific gravity.
Applications for Drilling Fluid Grades
