Bentonite

Overview: 

Bentonite is a natural clay mineral primarily composed of montmorillonite, characterized by its remarkable water absorption and swelling properties. HexaHessman offers bentonite in powder and lump forms, suitable for a wide range of industrial applications including drilling, foundry, and environmental uses.

Key Features:

• Superior swelling capacity and water retention, enhancing performance in drilling muds and sealing applications.
• High cation exchange capacity for improved chemical interaction and absorption.
• Non-toxic and environmentally friendly, making it safe for industrial and environmental applications.
• Available in multiple grades (Sec: 9, 10, 11) to suit specific process requirements.

Applications:

• Essential component in drilling muds for oil and gas exploration.
• Used in foundry sands and casting processes to improve mold integrity.
• Helps in iron ore pelletization for steel production.
• Utilized in cat litter, sealants, and environmental containment applications.
