• China kaolin clay price 4000 mesh calcined kaolin for paint, plastic, rubber industry, adhesives, wires and cables

4000 mesh calcined kaolin is a calcined product of coal-measure kaolin, characterized by high whiteness, fine particles, porous surface and higher surface.Therefore, it has good dispersibility and suspension in water base or oil base, which can effectively prevent the deposition of the coating and give the coating a good canning effect.4000 mesh calcined kaolin is chemically inert, does not react with acid and alkali at room temperature, thus can improve the weather resistance, scrub resistance, wear resistance of the coating.


4000 mesh calcined kaolin clay

Compared with uncalcined kaolin, calcined kaolin has lower content of bound water, higher content of silica and alumina, higher activity point, different structure, smaller and uniform particle size.Kaolin is a kind of nonmetallic mineral which is ubiquitous in nature.Calcined kaolin is widely used in ceramics, rubber, plastics, artificial leather, cement, refractory, chemical and other industries as well as agriculture.With the further improvement of the beneficiation technology of Gaolaceite, the application of kaolin will be more and more extensive.IMRI supplies all kinds of calcined kaolin clay such as 325 mesh calcined kaolin,1250 mesh calcined kaolin,4000 mesh calcined kaolin,6250 mesh calcined kaolin,etc.

Applications: Paint, plastic rubber, building materials, adhesives, wires and cables.
