Bentonite Powder Application: Chemical Industry

Bentonite is a highly absorbent, viscous plastic clay which is a valuable binding, sealing, absorbing and lubricating agent in a huge variety of industries and applications.

Bentonite is a very soft plastic clay consisting predominantly of montmorillonite, a fine particle-sized hydrous aluminum silicate and member of the smectite group. Most bentonites are formed by the alteration of volcanic ash and rocks after intense contact with water. Bentonite presents strong colloidal properties and increases its volume several times when coming into contact with water, creating a gelatinous and viscous substance. Its specific properties include swelling, waterA absorption, viscosity, and thixotropy. These properties are in demand in a huge range of industries served by Imerys, earning it the nickname a the mineral with a thousand usesa .
