It is a layered silicate, with one tetrahedral sheet linked through oxygen atoms to one octahedral sheet of alumina octahedral.  It has a low shrink-swell capacity and a low cation exchange capacity. Therefore China Clay does not swell on adding water & Alumina present in Clay do not form Isomorphous series with any other metallic compound. The Micronized China Clay Powder can withstand high temperature and also increases the strength of the material in which it is mixed.

 

Widely used in polymer applications, Micronized China Clay Powder contributes to the improvement in chemical resistance, electrical properties and reduction in water absorption. It lowers the crack tendency in the finished products, improves shock resistance and surface quality. It is one of the most abundantly available clay in the Earth's crust. A large variety of china clay is mined all over India. In orders to ensure that our clients receive a flawless range of products; these are tested on various parameters predefined by the industry.
