Product Introduction

Bentonite is a natural clay mineral mainly composed of montmorillonite. Due to its unique layered structure and strong water absorption ability, bentonite has excellent swelling, viscosity, adsorption, and sealing characteristics.
When bentonite comes into contact with water, it can absorb water and expand significantly, forming a gel-like structure with good stability and sealing performance. This unique property makes bentonite clay an ideal material for applications requiring water retention, binding, thickening, filtration control, and sealing functions.
Yandong's high quality bentonite is available in different grades according to customer requirements, including sodium bentonite, calcium bentonite, activated bentonite, drilling grade bentonite, foundry grade bentonite, and pet litter grade bentonite.
Through professional mineral processing technology and strict quality control, our bentonite products maintain stable swelling capacity, uniform particle size, and excellent application performance.

Product Description

Natural bentonite clay is a versatile mineral material with excellent physical and chemical properties. Its main component, montmorillonite, provides strong adsorption capacity and expansion performance.
In the pet industry, bentonite is widely used as a raw material for cat litter production. Due to its high absorbency and clumping ability, bentonite cat litter can quickly absorb moisture and form solid clumps, making cleaning easier and improving user experience.
In the drilling industry, sodium bentonite is an important material for drilling fluids. Drilling grade bentonite provides viscosity, lubrication, and filtration control, helping stabilize boreholes and improve drilling efficiency.
In the foundry industry, bentonite works as a binding material for molding sand. Its excellent bonding properties help improve mold strength and casting quality.
In the construction industry, bentonite is used for waterproofing, slurry walls, tunneling projects, and geosynthetic clay liners due to its swelling and sealing characteristics.
In agriculture, bentonite can be used as a soil amendment material to improve soil structure, increase water retention, and enhance nutrient holding capacity.
Yandong's bentonite is produced according to different application requirements, providing customers with suitable mineral solutions for various industries.
