Heavy spar

Heavy spar is a natural barium sulfate used in industry as a functional filler and as a raw material in chemical processes. The product is used in plastics, rubber, coatings, sealants, and drilling fluids, among others, where high density and chemical inertness are important.

Due to its high specific gravity, Heavy spar contributes to weight build-up, stability, and consistent product composition. The material is poorly soluble in water and reacts hardly at all with many other substances. As a result, it is suitable for applications where process reliability, low reactivity, and reliable performance are required.

In industrial formulations, heavy spar supports properties such as wear resistance, viscosity control, and uniform distribution in the final product. For buyers and technical users, it is a relevant choice when density, chemical resistance, and a stable mineral filler are key.
