Bentonite: A Versatile Raw Material for Industrial and Commercial Use
Bentonite is a naturally occurring clay mineral known for its unique properties, including high absorbency, swelling capacity, and binding strength. Widely used in industries such as construction, agriculture, and cosmetics, Bentonite is a critical raw material for various applications. This guide explores its types, features, and how to source it effectively.
How to Find Reliable Bentonite from China in 2025
China is a leading supplier of Bentonite, offering competitive prices and high-quality products. To find reliable suppliers, consider platforms like Alibaba, where verified manufacturers list their products. Look for suppliers with certifications such as ISO 9001 and positive customer reviews.

What Buyers Should Know Before Buying Bentonite from China
When purchasing Bentonite from China, ensure the supplier provides detailed product specifications, including moisture content, particle size, and swelling index. Verify shipping terms, payment methods, and lead times. It's also advisable to check for any import regulations in your country to avoid delays.
Types of Bentonite
There are two primary types of Bentonite: Sodium Bentonite and Calcium Bentonite. Sodium Bentonite has high swelling capacity and is ideal for sealing and binding applications. Calcium Bentonite, on the other hand, is less absorbent and commonly used in cosmetics and pharmaceuticals.
Functions and Features of Bentonite
Bentonite is valued for its ability to absorb water, swell, and form gels. It also has excellent binding properties, making it useful in foundry molds, drilling muds, and cat litter. Its high cation exchange capacity allows it to remove impurities in water treatment processes.
Scenarios of Bentonite
Bentonite is used in diverse industries. In construction, it acts as a sealant for ponds and landfills. In agriculture, it improves soil water retention. The cosmetic industry uses it in face masks for its detoxifying properties. It's also a key ingredient in pet care products like clumping cat litter.
How to Choose Bentonite
Selecting the right Bentonite depends on your application. For sealing purposes, Sodium Bentonite is preferred due to its swelling capacity. For cosmetic or pharmaceutical use, Calcium Bentonite is more suitable. Always check the purity and particle size to ensure it meets your requirements.
