Barium Sulfate / Barite

Precipitated Grade
Precipitated Barium Sulfate is a high brightness, low oil absorption, inert extender that is well suited for a variety of application including powder coatings, thermoplastics, elastomers, fiber, paper, ink and pigment preparations.

Precipitated Barium Sulfate has a Mohs hardness of 3 and is very low in abrasion. It exhibits a continuous, high diffuse reflectance of light, not only in the visible range, but also far into the UV and IR ranges. It is the ideal extender of colored systems. In coatings, Precipitated Barium Sulfate is recommended in high gloss, acid-resistant formulations.

Precipitated Barium Sulfate is inert, resistant to light and weathering, and insoluble in water, acids, alkali and organic media.

Pigment Grade
These fine white barites are natural, select, white, high quality material designed for use in paints and coatings, plastics and other applications requiring a white and/or acid resistant high density filler.

Our Pigment Series Barium Sulfates are high density, low oil absorption, very white, acid resistant fillers. The specific gravity is 4.25, the oil absorption is 10 – 13 depending on the grade, dry brightness is 90 min., and the Mohs’ hardness is 3.0 – 3.5. Like the Blanc Fixe, the Barium Sulfate can contribute to corrosion resistance.

Chemical Grade
These barites are designed for use in plastics, paints, coating, brake linings and other applications requiring acid resistant, high-density filler.

Our Chemical Series is a lower color Barite which gives the formulator the same qualities as the Pigment Series Barite’s but the option of using a lower cost Barite in darker color applications. The dry brightness of the this Series Barite’s is 80 – 82 minimum.
