Bentonite
CAS NO.: 1302-78-9
A. Product characteristics and uses:
Bentonite has special properties, such as swelling power, cohesiveness ,catalysis, thixotropy, suspension property and cation exchange property and so on, so it is widely used in various industrial fields. according to the uses, bentonite is divided into bentonite for mechanical casting use, bentonite for metallurgy pellet, bentonite for drilling mud, bentonite for agricultural building materials, bentonite for civil engineering.
