Bentonite is a natural occurrence material dominantly the Clay Mineral Montmorillonite. It is having a layered structure that possesses High Swelling properties and High Cation exchange capacities. When in contact with water it expands up to Twenty to Forty times its dry volume. Depending upon the dominant exchangeable cations present the clay may be referred as Calcium Bentonite or Sodium Bentonite, the two varieties exhibiting different properties and thus, uses. There are three main characteristics of Bentonite that make it commercially useful. They include Thixotropy, Swelling, and Adsorption.
The range of bentonite are suitable for us in Plastics and Polymer, Paper and boards, Const Chemicals, cosmetic, drilling fluids etc.
Microgel – Sodium Bentonite Economical bonding material in the molding processes associated with metal casting industry. With High montmorillonite content, Bentonite when mixed with foundry molding sands, forms pliable bond with sand particles. It provides good compaction, clean knockout and permeability. Microgel has unique bonding characteristics that ensure the durability of the mould.
Nanobond – High Thermal Bentonite Blended Bentonite powder designed to give high thermal stability along with high compression and tensile strengths, to produce high quality grey and ductile iron castings with smooth surface finish. Reclamation of Bentonite while maintaining the required MB Value for green sand molds Reduction in waste disposal issues.
Micron Blend C – Carbon Coated Bentonite Micro blend is a customized blend of high quality bentonite and carbonaceous additives suit to individual foundry requirements.
