Description

Attapulgite is a naturally occurring, hydrated magnesium aluminum silicate clay mineral prized for its unique colloidal and sorptive properties. Its high surface area and fibrous structure make it an exceptionally effective thickener, binder, and adsorbent across diverse industrial applications. This versatile material is essential for manufacturers in sectors ranging from agriculture and construction to oilfield services and environmental remediation, where performance and reliability are critical.

Application

• Drilling Fluids: A key component in water-based and saltwater drilling muds, where it acts as a viscosifier and filtration control agent to stabilize boreholes.
• Agricultural Products: Used as a carrier and suspending agent in pesticide and herbicide formulations, and as a soil conditioner to improve moisture retention.
• Industrial Absorbents: Employed in granular or powdered form to absorb oils, greases, and hazardous liquid spills in industrial and environmental cleanup operations.
• Paint & Coatings: Functions as a rheology modifier and thickener to prevent sagging and settling in paints, adhesives, and sealants.
• Animal Feed & Litter: Utilized as an anti-caking agent in feed and as an odor-control absorbent in pet litters.
• Catalyst & Carrier: Serves as a support material or catalyst carrier in various chemical processes due to its porous structure.
• Pharmaceuticals & Cosmetics: Used in limited applications as an adsorbent or viscosity-increasing agent in certain formulations.
• Construction Materials: Acts as a binder and plasticizer in specialty cements, mortars, and grouts.

Quality Control

Our Attapulgite is sourced and processed under strict quality protocols to ensure batch-to-batch consistency and performance. Quality is verified through a series of tests including viscosity, moisture content, particle size distribution, and adsorption capacity. While available in various industrial and technical grades, our production can align with relevant industry specifications. A Certificate of Analysis (COA) detailing key parameters is provided with every shipment.

Storage

Preserve in a tightly closed container, protected from light. Due to its hygroscopic (moisture-sensitive) nature, store in a cool, dry, and well-ventilated area at room temperature (15-25°C). Keep containers tightly sealed when not in use to prevent moisture absorption and caking. Store away from incompatible materials.
