About this product

Product information from the supplier.

Our Premium Natural Bentonite Clay is a high-performance mineral solution engineered for industrial excellence. Specifically designed with a high swelling rate and superior viscosity, our Sodium and Calcium Bentonite powders serve as critical additives in drilling muds, high-grade coatings, and civil engineering projects. Composed primarily of montmorillonite, this clay possesses an extraordinary ability to absorb up to 8 times its own volume of water, providing exceptional stability and lubrication in the most demanding environments.

By leveraging a unique cation exchange capacity and strong thixotropic properties, our bentonite ensures optimal fluid suspension and wellbore integrity for oil and gas exploration, while offering precise thickening and binding capabilities for the chemical and foundry industries. From environmental remediation to advanced construction sealing, our ISO-certified bentonite delivers consistent, reliable, and sustainable results for global industrial applications.

Frequently Asked Questions

Q: What is the difference between Sodium Bentonite and Calcium Bentonite?

Sodium Bentonite has a significantly higher swelling capacity and viscosity, making it ideal for drilling muds and sealing. Calcium Bentonite is generally used as a binder in foundry applications and as a filler in other industrial processes.

Q: How does bentonite improve drilling mud performance?

It creates a thixotropic gel that supports the weight of the drill, lubricates the bit, and forms a "filter cake" on the wellbore wall to prevent collapse and fluid loss.

Q: Can this product be used for wastewater treatment?

Yes, due to its high adsorption and ion exchange capacity, it is excellent for clarifying industrial effluents and absorbing contaminants from steel and electroplating factory sewage.

Q: What mesh sizes are available for your bentonite powder?

We provide a comprehensive range from 20 mesh to 3000 mesh, with 325-1250 mesh being the most common for industrial coatings and specialized drilling applications.

Q: Is your bentonite environmentally sustainable?

Absolutely. Our bentonite is a naturally occurring mineral sourced responsibly. It is frequently used in eco-friendly projects such as landfill containment and soil remediation.

Q: How should bentonite be stored and packaged?

Our product is supplied in durable 50 kg bags. It should be stored in a cool, dry area to prevent premature moisture absorption and maintain its high swelling potential.
