Talc Powder (Hydrous Magnesium Silicate) Product Introduction

Talc Powder is a high-performance layered silicate mineral powder widely recognized as the softest natural industrial mineral. With excellent lubricity, chemical inertness, high-temperature stability and low abrasion, talc powder serves as a core functional filler and modifier in plastics, rubber, coatings, papermaking, cosmetics and pharmaceutical industries. Mined from natural talc ore and processed through crushing, purification, ultra-fine grinding and classification, it delivers stable physical and chemical performance, making it an indispensable raw material for modern high-end manufacturing.
