Bentonite CAS#1302-78-9
Superior Swelling & Water Absorption Capacity: Natural montmorillonite mineral powder with huge specific surface area, strong water absorption, can expand dozens of times its original volume after absorbing water, forming stable thixotropic slurry.Excellent Thickening & Anti-settling Effect: Obvious thickening, suspending and lubricating performance, effectively prevent solid particles from precipitation, keep uniform system stability in coating, drilling mud and daily chemical products.Stable Chemical Inertness: Chemically inactive under normal temperature, resistant to weak acid and weak alkali, non-toxic odorless, good compatibility with most water-based and oily raw materials.Diversified Functional Applications: Multiple modified grades available (sodium-based, calcium-based, organic bentonite), widely applicable in mineral exploitation, building materials, coating, feed and environmental protection industries.
Product Details
