Sodium Bentonite

High Swelling Bentonite Clay for Drilling & Industrial Applications

Product Summary

Sodium Bentonite — Sodium Bentonite is a naturally occurring high-swelling clay composed primarily of sodium montmorillonite. It exhibits excellent water absorption, swelling capacity, viscosity, and sealing properties. Sodium Bentonite is widely used in drilling fluids, civil construction, waterproofing systems, foundry casting, and environmental sealing applications.

Applications

  • Oil & Gas Drilling Fluids — Used as a primary viscosifier and filtration control agent in drilling mud systems.
  • Water Well & HDD Drilling — Provides borehole stability and lubrication in water well and horizontal drilling.
  • Pile Foundation & Diaphragm Walls — Stabilizes boreholes and trench walls during civil and infrastructure construction.
  • Geosynthetic Clay Liners (GCL) — Used in landfill liners, ponds, canals, and containment systems for waterproofing.
  • Foundry Casting — Acts as a binder in green sand molds, improving strength and thermal resistance.
  • Environmental Sealing & Waste Containment — Used to prevent leachate migration in waste disposal and remediation projects.
  • Civil Engineering & Tunneling — Applied for ground stabilization and slurry wall construction.
  • Export Supply for Infrastructure Projects — Supplied in bulk for large-scale drilling, construction, and environmental projects.
