Description

Diatomaceous Earth is a naturally occurring, soft, siliceous sedimentary rock composed of the fossilized remains of diatoms. This unique composition provides a highly porous structure with exceptional filtration capabilities and a high surface area, making it a versatile and valuable industrial material. It is widely utilized across numerous sectors, including food & beverage processing, water purification, agriculture as a natural pesticide, and as a functional filler in paints, plastics, and pharmaceuticals.

Application

• Filtration Aid: Used extensively in the filtration of beverages (beer, wine, juice), edible oils, syrups, pharmaceuticals, and industrial chemicals to achieve clarity and remove fine particulates.
• Natural Insecticide: Acts as a mechanical pesticide in agriculture and stored grain protection, dehydrating insects through physical action.
• Functional Filler & Extender: Improves texture, bulk, and absorbency in paints, coatings, plastics, rubber, and construction materials like asphalt and cement.
• Absorbent Material: Used for spill cleanup (e.g., oils, chemicals), in cat litter, and as a stabilizer in nitroglycerin for dynamite.
• Carrier & Anti-caking Agent: Serves as a carrier for active ingredients (e.g., pesticides, catalysts) and as an anti-caking agent in fertilizers and animal feed.
• Polishing & Abrasive Agent: Employed in mild abrasive applications such as metal polishes, toothpaste, and facial scrubs.
• Soil Amendment: Enhances soil aeration and water retention in horticulture and gardening.
• Thermal Insulator: Used in certain high-temperature insulation applications due to its stability.

Quality Control

Our Diatomaceous Earth is produced and tested to meet stringent quality standards for its intended applications. We offer various grades, including Food Chemical Codex (FCC) and Feed Grade, with specifications for purity, particle size distribution, and permeability. Certificates of Analysis (COA) documenting key parameters are available upon request to ensure compliance with your specific requirements.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area away from incompatible materials. Keep containers sealed when not in use to prevent moisture absorption and contamination. Standard room temperature (15-25°C) conditions are typically suitable.
