Properties
Swelling is mainly due to two factors: 1) water absorption at platelet surface level, and 2) osmotic repulsive forces, forcing platelets to detach and open up like a "stack of cards". Sodium bentonite, with sodium cation prevalence (Na+) allows water to penetrate through the platelets, forcing them apart, thus leading to swelling.
