Commonly known as bentonite clay, clay mineral montmorillonite minerals mainly composed by. Good water swelling, adhesion, adsorption, catalytic activity, thixotropy, suspension, plasticity, lubricity and cation exchange and a series of special physical and chemical function.
1. Proven to be one of the most effective sealants on the market
2. Swells much larger than its mass, then forms a strong water & chemical proof
3. Sodium bentoniteproduced by a naturally occurring mineral, environmentally-friendly
4. Acts as a hydrated aluminum silicate & it is a rock composed of crystalline clay like Montmorillonite Mineral clay
5. High swelling & gelling properties
6. Strong viscosity with excellent colloidal properties
7. Animal feed grade
8. Fertilizer grade
9. Cosmetic grade
10. Cement/drilling factory

What's Bentonite?
Bentonite is one of most popular clays and comes from naturally occurring volcanic ash sediments here in the China. Bentonite clay has been traditionally used to assist in mineral deficiencies, and to help bind toxins making them more soluble. Bentonite, also referred to as Montmorillonite, is one of the most effective and powerful healing clays.
Bentonite has the great expansibility under water and a good colloidal nature properties.It can increase the viscosity of suspension in the drilling mud when used.Increasing the lubrication of drilling and cleaning produces in the process of drilling cuttings, it is widely used to complex geological structure formation drilling construction, to prevent hole-accidents. The products are known for its good performance, strong water hydration expansion, big cation exchange capacity and high made pulp rate.
