Kaolin Clay, also known as China Clay, is a soft white mineral rich in kaolinite. It is processed from naturally occurring deposits by washing, refining, and drying. Kaolin is widely used in ceramics, paper, paint, rubber, plastics, and cosmetics industries. In paper, it improves brightness and smoothness; in paints, it enhances coverage and durability. Its fine texture and chemical stability make it ideal for industrial and beauty applications. We supply premium-grade kaolin with consistent quality.
