TECHNICAL SPECIFICATION
Sodium, calcium and activated bentonite selected by application
Bentonite performance depends on mineral type and end use. Drilling, foundry, pelletizing, civil-engineering, ceramic and cat-litter applications require different rheology, swelling, bonding, absorption and particle-size criteria. Numeric specifications are published only from approved technical records.
Technical values are provided according to the selected grade and applicable TDS or COA.
