What is Bentonite Clay?
Bentonite clay is a naturally occurring mineral composed mainly of montmorillonite, valued for its ability to expand multiple times its original volume when hydrated.
It is widely used in drilling, foundry molds, civil engineering, agriculture, and environmental sealing due to its chemical stability, water retention, and binding strength.
At Puresil India, our bentonite clay is processed to ensure uniform particle size, purity, and industrial-grade performance.
