Bentonite / Grade Selection
Bentonite Grade Selection Guide for Drilling, Foundry, and Civil Buyers
How buyers shortlist bentonite grades by application and avoid mismatched trials.
Map grade to application performance
Bentonite buying should be led by function: swelling behavior, viscosity response, and moisture stability.
- Define exact application: drilling, foundry, piling, HDD, earthing, or sealing.
- Share process condition where rheology matters.
- Confirm handling and storage realities at destination.
Clarify form and usage plan
Lumps and powder behave differently in handling and blending systems.
- Choose supply form based on your dosing method.
- Share expected monthly volume and trial target.
- Ask for grade consistency approach for repeat shipments.
Commercial fit should follow technical fit
Quoting first and qualifying later often increases cost and delay.
- Confirm grade shortlist before rate comparison.
- Align packing and shipment terms to your site setup.
- Keep documentation and dispatch updates in one owner flow.
