2. Product Overview
Bentonite is a naturally occurring clay mineral composed primarily of montmorillonite, an aluminosilicate with a layered structure. Its unique properties — including high swelling capacity, cation exchange capacity, and thixotropic behavior — make it indispensable in a wide range of industrial applications. Sodium bentonite, in particular, is known for its high swelling value and excellent colloidal properties, making it the preferred grade for drilling fluids and foundry applications.
Iranian sodium bentonite is characterized by a montmorillonite content of ≥85%, a swelling value of ≥24 ml/2g, and a pH of 8.0–10.0. It meets API 13A standards for drilling-grade bentonite, ensuring reliable performance in oil and gas exploration. In foundry applications, bentonite is used as a binder in molding sands, providing green strength and thermal stability. In ceramics, it improves plasticity and green strength of tile and sanitaryware bodies. In purification, bentonite is used as an adsorbent for oils, fats, and wastewater treatment. In cosmetics, it serves as a thickener and adsorbent in face masks and creams. In animal feed, it acts as a pellet binder and anti-caking agent.
