Bentonite is a kind of hydrous clay mine as the main component of montmorillonite,
CAS: 1302-78-9
Chemical formula of Bentonite is: Al2O3.4(SiO2).H2O
Molecular Structural Formula: 
Montmorillonite's Chemical formula: (Al2,Mg3)[Si4O10][OH]2·nH2O.
Based on bentonite's special qualities like the property of Swelling, cohesiveness, adsorption, catalysis, thixotropy, suspension, and cation exchange, it has been widely used in different industries. Actually It has been put into use in over 100 departments in the 24 fields ofindustrial and agricultural production and it has been made into over 300 kinds of production, this is why people call it "omnipotent clay".
All the montmorillonite-related products of our company are made with the best quality bentonite, which has over 95% montmorillonite content. This makes our products have excellent function like moisture absorption, static dehumidification, deodorizing, and advantage like high adsorption rate and good absorptive capability.
Montmorillonite is non-toxic, tasteless, non-corrosive and no environmental pollution, and it does not contain any additives or calcium chloride. It is a new type of environmental protection mineral which is 100% degradable and can be reused if it doesn't degenerate in low-temperature environment. The related products can be widely applied in different industries like food, medicine, electronic products, military and container shipping.
