    Physical properties Bentonite is an hydrated natural clay mineral dominated by montmorillonite. Bentonite is mainly white, cream colored, light gray, yellowish green, black, variegated, etc, it is mostly dense and hard, a little earthy, and it has strong swelling power. Outcrop or foamy on the outcrop oil sheen, waxy sheen or earthy sheen, opaque. Hardness 2.0 ~ 2.5 Specific.Bentonite presents strong colloidal properties and its volume increases several times when coming into contact with water, creating a gelatinous and viscous fluid. The special properties of bentonite (hydration, swelling, water absorption, viscosity, thixotropy) make it a valuable material for a wide range of uses and applications.
