Product Description

Product Description

Bentonite is a kind of water bearing clay ore mainly composed of montmorillonite, because of its special properties, Such as : swelling, cohesiveness, adsorption, catalysis, thixotropy, suspension, cation exchange, etc.When the interlayer cation is Na +, it is called sodium bentonite; When the interlayer cation is Ca2 +, it is called calcium bentonite.

Calcium Bentonite is white or gray white powder , insoluble in water, oil and organic solvent. It has strong adsorption capacity. It is non toxic, good thermal stability, fast filtering speed, low oil rate.
