General Description
Kaolin is a naturally occurring hydrated aluminum silicate mineral widely used across ceramics, paper, rubber, paints and coatings, personal care, pharmaceuticals, and industrial applications. It is valued for its fine particle size, chemical inertness, high brightness, and excellent dispersibility.
Kaolin functions as a filler, extender, anti caking agent, absorbent, and rheology modifier depending on application. Its low abrasiveness, thermal stability, and consistent quality make it suitable for both technical and regulated formulations.
