Product Overview

Talc, Mg₃Si₄O₁₀(OH)₂, is renowned for being the softest mineral on the Mohs scale. At Ridhi Sidhi Microns, we manufacture high-purity industrial talc powder from carefully selected ore deposits in Rajasthan. The unique crystal structure of talc gives it a platy particle shape, responsible for superior barrier properties, improved surface finish, and reduced warpage in polymer parts. In the plastics industry, talc significantly improves stiffness, heat deflection temperature, and dimensional stability in polypropylene. For paints, talc improves film integrity and moisture resistance. In paper, talc serves as a pitch control agent. In cosmetics and pharma, talc is valued for softness and absorbency. We supply talc in grades from 200 to 500 mesh, with purity levels from 90% to 98%.
