Virtual International supplies high-performance Bentonite Powder, a natural absorbent clay mineral composed primarily of montmorillonite. We carefully select and process our sodium bentonite to maximize its exceptional swelling, gelling (thixotropic), sealing, and binding capabilities. When hydrated, our bentonite powder forms a viscous, low-permeability slurry, making it an indispensable material for demanding applications. Industries from civil engineering and oil & gas drilling to metal casting and agriculture rely on our consistent, high-quality bentonite to ensure process reliability and superior results.

Key Features & Benefits

• Exceptional Swelling Capacity: Our bentonite expands significantly when it contacts water, creating a highly effective and permanent hydraulic barrier.
• Superior Viscosity & Thixotropy: It creates a shear-thinning gel that is viscous at rest but flows when agitated, perfect for suspending solids in drilling fluids and slurries.
• Excellent Binding Strength: It acts as a powerful binder for sand in founDry molds and for fines in the pelletizing of animal feed and iron ore.
• Low Permeability: The impermeable gel it forms makes it an ideal sealant for landfills, ponds, lagoons, and subsurface structural foundations.
• High Purity & Consistency: We provide a product with uniform particle size and mineralogy, which delivers predictable performance in every application.

Major Industrial Applications

Oil & Gas Drilling:

• As a primary component of drilling mud, it lubricates the drill bit, suspends rock cuttings, and seals the borehole wall to prevent fluid loss.

Civil Engineering & Construction:

• Engineers use it to create slurry walls, seal foundations, and waterproof subsurface structures.
• It is the key component in Geosynthetic Clay Liners (GCLs) for containment applications like landfills and canals.

FounDry & Metal Casting:

• It serves as the primary binding agent in “green sand” molding systems to create high-integrity molds for ferrous and non-ferrous castings.

Agriculture & Animal Feed:

• It improves pellet durability and hardness in animal feed manufacturing.
• It also functions as an effective mycotoxin binder, protecting animal health.
