Description

Celite is a high-purity, naturally occurring diatomaceous earth product widely used as a highly effective filtration aid and functional filler. Its unique skeletal structure provides exceptional surface area and porosity, making it a critical processing material for achieving clarity and purity in liquid streams. This product is essential for manufacturers and processors in the pharmaceutical, food and beverage, chemical, and industrial sectors requiring reliable solid-liquid separation.

Application

• Filtration Aid: Primary use in pressure and vacuum filtration to clarify beverages (beer, wine, juice), pharmaceuticals, chemicals, and oils.
• Pharmaceutical Processing: Used as a filter medium in the production of antibiotics, vitamins, and other active pharmaceutical ingredients (APIs).
• Food & Beverage Industry: Clarification and stabilization of sugars, syrups, edible oils, and alcoholic drinks.
• Industrial Catalyst Carrier: Serves as an inert, high-surface-area support material for catalysts in chemical synthesis.
• Functional Filler: Used in paints, coatings, plastics, and adhesives to modify rheology, improve matting, and reinforce structure.
• Agricultural & Horticultural Additive: Acts as a carrier for pesticides and fertilizers and as a soil conditioner.
• Absorbent Material: For spill control and as a component in pet litter and industrial absorbents.

Quality Control

Our Celite is produced and tested under a stringent quality management system to ensure batch-to-batch consistency and performance. We offer various grades, including Food Chemical Codex (FCC) and technical grades, tailored to specific industry requirements. A comprehensive Certificate of Analysis (COA) detailing physical and chemical specifications is provided with each shipment to guarantee compliance with your application needs.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at room temperature (15-25°C). Keep away from strong acids and strong alkalis. The product is hygroscopic (moisture-sensitive); ensure containers are sealed after use to prevent moisture absorption and caking.
