Sodium Bentonite Powder
MOQ 28 Ton · Seller will confirm final rate
Sodium Bentonite is a natural montmorillonite clay known for its high swelling capacity, strong water absorption, and excellent binding properties when hydrated. Key Characteristics & Applications High Swelling Capacity: Expands up to 15–18 times its dry volume in water, forming a gelatinous mass that creates effective hydraulic seals. Civil Engineering & Environmental: Widely used as a sealant for pond liners, landfills, foundation waterproofing, and bentonite slurries in diaphragm walls or drilling fluids. Foundry & Metallurgy: Functions as a high-strength green sand binder for iron and steel casting molds. Industrial & Agricultural: Used as a pelletizing agent for iron ore, cat litter, animal feed additive, and wastewater treatment clarifying agent. Technical & Commercial Specifications Form: Powder or granules Color: Light grey, off-white, or tan Free Swelling Index: 20–30 mL/2g (minimum) Moisture Content: Max 10–12% pH Range: 8.5–10.5 (Alkaline) Packaging: 25 kg / 50 kg HDPE bags or 1000 kg Jumbo Bags
