OVERVIEW

Strontium Sulfate (SrSO₄)

CelesBar Strontium Sulfate is a naturally occurring, high-purity mineral engineered for demanding industrial applications where chemical resistance, thermal stability, brightness, and consistent particle size are critical. Produced from premium celestite ore, CelesBar undergoes advanced milling and quality control processes to deliver a reliable, high-performance functional filler for a variety of applications.

Unlike synthetic materials, CelesBar is manufactured from naturally occurring strontium sulfate deposits using a fully integrated supply chain—from mine to mill to market—allowing Cimbar to maintain exceptional quality, supply reliability, and product consistency.
