Superior Quality Bentonite
Unmatched swelling, sealing, and binding for modern industries.
Bentonite is a highly absorbent, fine-grained clay composed predominantly of montmorillonite, a mineral known for its remarkable swelling, binding, and sealing capabilities. When exposed to water, Bentonite expands significantly, forming a gel-like structure that offers excellent plasticity and adsorption properties. These characteristics make it one of the most versatile industrial clays, valued across multiple sectors for its natural performance and reliability.
Its unique combination of viscosity, thermal stability, and chemical inertness allows Bentonite to play a critical role in drilling operations, foundry applications, purification processes, agriculture, construction, cosmetics, and pharmaceuticals. From stabilizing boreholes in oil and gas drilling to acting as a binder in pelletizing and a sealant in waterproofing systems, Bentonite delivers consistent, high-quality results. Its exceptional filtration, absorption, and binding strength further enhance its importance in both industrial and consumer-grade products.
