Bentonite application in various industries

Bentonite is a non-metallic mineral with montmorillonite as the main mineral component. It is widely used because of its water absorption, swelling, cation exchange, thixotropic, cohesive, adsorptive, thickening and lubricity properties. In various industrial sectors.


Foreign countries have applied in more than 100 departments in 24 fields of industrial and agricultural production, and there are more than 300 products, so people call it “universal soil”.
