Overview of Sodium Bentonite

Sodium Bentonite is a naturally occurring clay mineral primarily composed of montmorillonite, known for its high swelling capacity, excellent water absorption, and binding properties. It appears as a fine off-white to light brown powder and is widely used across drilling, foundry, construction, agriculture, and water treatment industries.

Due to its superior viscosity, thixotropic behavior, and sealing ability, Sodium Bentonite is extensively used as a drilling mud additive, binder, absorbent, and sealing material. Its ability to swell multiple times its dry volume makes it an essential industrial mineral for various technical and environmental applications.

Related products available on our website and commonly used in similar applications include Calcium Bentonite, Bentonite Granules, Kaolin Clay, and Fuller’s Earth. These materials are widely applied in industrial processing, environmental protection, and mineral-based formulations.
