Bentonite in foundry industry.

Bentonite is natural high swelling sodium based bentonite of exceptional Purity And High Thermal Durability. It is sodium activated bentonite designed to meet the requirements of modern foundry set up especially high-pressure molding lines (Flask / Flaskless) and deep-drawn castings.

The use of bentonite imparts a Low Specific Burnout Ratio in molding sand due to its High Purity & Thermal Durability. Bentonite does not contain any Fermentable Product and is Environmentally Acceptable.
