Kaolin / China Clay – Product Overview

Our Kaolin (China Clay) is a high-quality, naturally occurring clay mineral used across ceramics, paper, paints, rubber, and other industries.

Processed to deliver consistent whiteness, controlled particle size, and low impurity levels, it supports stable production and high-quality finished products.

With reliable supply and technical support, we help manufacturers optimize formulations and achieve repeatable performance in demanding applications.
