Description

Attapulgite is a naturally occurring, hydrated magnesium aluminum silicate clay mineral prized for its unique colloidal and sorptive properties. This versatile material serves as a highly effective rheological modifier, absorbent, and carrier across numerous industrial processes. Key industries that rely on its performance include oil & gas drilling, agriculture, paints & coatings, and environmental remediation. Our high-quality Attapulgite CAS NO 1337-76-4 is sourced and processed to meet the stringent demands of global B2B customers.

Application

• Drilling Fluids (Muds): Acts as a primary viscosifier and filtration control agent in water-based and salt-saturated drilling muds for oil, gas, and geothermal wells.
• Agricultural Products: Used as a carrier and suspending agent in pesticides, herbicides, and liquid fertilizers, and as an anti-caking agent in animal feed.
• Paints, Coatings, and Inks: Functions as a rheology modifier (thixotrope) to prevent sagging, settling, and splattering, improving application properties.
• Absorbents and Desiccants: Utilized in granular or powdered form to absorb oils, greases, and liquids in industrial spill control, pet litter, and packaging.
• Catalyst & Chemical Carrier: Serves as an inert support or active catalyst carrier in various chemical synthesis and refining processes due to its high surface area.
• Pharmaceuticals and Cosmetics: Employed as an adsorbent, viscosity-increasing agent, or suspending agent in medicinal and personal care formulations.
• Foundry & Binder Applications: Used as a bonding agent in foundry sands and as a binder in pelletized products like animal feed and fertilizers.
• Environmental Remediation: Applied in filtration systems and as an additive for stabilizing contaminants in soil and wastewater treatment.

Quality Control

Our Attapulgite is produced under a strict quality management system to ensure batch-to-batch consistency and performance reliability for industrial applications. While specifications vary by grade (e.g., Drilling, Agricultural, Pharmaceutical), all material is tested for key parameters such as viscosity, particle size distribution, moisture content, and absorption capacity. We adhere to relevant industry guidelines and Certificates of Analysis (COA) are available upon request to support your quality assurance protocols.

Storage

Preserve in a tightly closed container, protected from light. This product is hygroscopic (moisture-sensitive) and must be stored in a cool, dry, and well-ventilated area at room temperature (15-25°C). Keep the container tightly sealed when not in use to prevent moisture absorption and caking. Store away from incompatible materials.
