Application

Our water washed China clay (Kaolin) is used in ceramic products, insulators, and refractory. In ceramic product, China clay (Kaolin) aids accurate control of molding properties, and adds dry and fired strength, dimensional stability, and a smooth surface finish to the ware. The excellent dielectric properties and chemical inertness of China clay (Kaolin) make it well suited for porcelain electrical insulators. In refractory applications, the dimensional stability, high fusion point, and low water content, along with high green strength, make water washed China clay (Kaolin) an important constituent.

Water washed China clay (Kaolin) is used as a filler in many rubber goods. It adds strength, abrasion resistance, and rigidity to both natural and synthetic rubber products. In general, most rubber products extrude more easily after China (Kaolin) filler is added. The major reason that kaolin is used in rubber compounds is its whiteness and low cost. Although China clay (Kaolin) costs less than most other rubber pigments, it has excellent functional properties.

Water washed China clay (Kaolin) has been used in paper making industries for many years, both as a coating pigment and as a filler to replace fiber. China clay (Kaolin) is especially suited for paper applications because it possesses desirable optical properties, is generally chemically inert and is also relatively inexpensive when compared to other minerals.
