Boric Acid (Technical Grade, Granular, Low Sulphate)

Boric Acid Technical Grade Granular Low Sulphate is a premium-grade orthoboric acid produced by Eti Maden, delivering the same exceptional purity as the standard technical grade — with a significantly reduced sulphate content of just 130 ppm maximum, less than half that of the standard powder grade. The granular particle size distribution, tightly controlled between 0.063 mm and 1.000 mm, makes it the preferred choice for applications where dust reduction, improved flowability, and easier handling are priorities. With B₂O₃ content of 56.25–56.90% and H₃BO₃ purity reaching up to 101.07%, it meets the most demanding specifications in sensitive production environments.
