High Versatility and Performance

Bentonite Powders natural swelling, oil absorption, and binding properties make it indispensable in industries such as drilling, foundry, and civil engineering. Sodium and calcium bentonite grades offer tailored benefits for specific applications, while its fine particle size ensures uniformity in various formulations. Its environmental friendliness and inertness further enhance its appeal.

Quality and Customization

Available as technical and industrial grades, this bentonite powder meets IS:6186 standards and offers over 95% purity (varies by supplier). Customizable mesh sizes cater to diverse requirements, while the products stable pH (810) and consistent density ensure reliable performance across industrial, cosmetic, and agricultural scenarios.

FAQs of Bentonite Powder:

Q: How is bentonite powder typically used in industrial and agricultural applications?

A: Bentonite powder is commonly used as a drilling mud in oil and gas exploration, a binding agent in foundries, and a soil conditioner in agriculture. Its swelling properties and cation exchange capacity enhance stability and nutrient retention in these settings.

Q: What makes sodium bentonite different from calcium bentonite?

A: Sodium bentonite swells significantly when mixed with water and is ideal for sealing and drilling mud, while calcium bentonite has less swelling capacity but provides better binding, making it suitable for foundry and construction applications.

Q: When should I use bentonite powder in cosmetic or pharmaceutical formulations?

A: You should use bentonite powder when you need natural thickening, absorption, or cleansing properties in masks, creams, or ointments. Its high purity and inert nature make it suitable for skin and pharmaceutical uses, subject to regulatory approval.

Q: Where is the best place to store bentonite powder to maintain its quality?

A: Store bentonite powder in a cool, dry area away from moisture to prevent clumping and preserve its swelling and absorption properties. Proper storage ensures the products longevity and effectiveness.

Q: What benefits does bentonite powder provide as a binding and absorbent material?

A: Bentonite powders fine particle size enables excellent binding and absorption of oils and impurities. These attributes are especially beneficial in foundry applications, wastewater treatment, and cosmetics where efficient absorption and stability are key.

Q: How is bentonite powder processed before it is ready for industrial use?

A: After mining, bentonite clay is crushed, dried to reduce moisture, and milled to the desired mesh size. Quality control ensures it meets the required specifications for industrial, cosmetic, or agricultural applications.

Q: What standards and specifications apply to bentonite powder supplied in India?

A: Bentonite powder usually adheres to IS:6186 standards for technical and industrial grades, and must meet purity, particle size, and performance criteria set by Indian regulations and industry requirements.
