Overview
Sodium Bentonite (Na-Montmorillonite) Powder/Granular is a premium-quality product supplied by ZEAL BIOTECH under strict quality management with full batch traceability. Sodium bentonite leads in drilling mud, foundry molding sand, waterproofing/geosynthetic clay liners and pond sealing, and is used as a high-performance pellet binder, cat-litter absorbent and premix carrier; in feed it binds pellets and adsorbs aflatoxin but its strong swelling means lower inclusion than calcium bentonite.
