Description

Silicap CAS NO 54480-08-9 is a high-purity, synthetic calcium silicate compound widely utilized as a versatile functional additive. Its primary value lies in its exceptional performance as a free-flow agent, anti-caking agent, and carrier material, enhancing the physical properties and stability of various formulations. This product is essential for manufacturers in the food, pharmaceutical, and industrial chemical sectors seeking to improve product quality and process efficiency.

Application

• As a highly effective anti-caking and free-flow agent in powdered food products, seasonings, and food additives.
• Utilized as a carrier and excipient in pharmaceutical tablets and nutritional supplements to ensure uniform active ingredient distribution.
• Acts as a filter aid and clarifying agent in beverage and food processing industries.
• Employed as a desiccant and moisture regulator in packaging and industrial applications due to its hygroscopic nature.
• Serves as a reinforcing filler in rubber, plastics, and sealants to improve mechanical properties.
• Used in paint and coating formulations as a flatting agent and to control rheology.
• Applied in agricultural chemicals as a carrier for pesticides and fertilizers to prevent caking.
• Functions as an adsorbent in various purification and separation processes.

Quality Control

Our Silicap is manufactured under a strict quality management system to ensure batch-to-batch consistency and reliability. Quality is verified against stringent in-house specifications, which may include parameters for purity, particle size, bulk density, and moisture content. We provide full traceability and Certificates of Analysis (COA) are available for every shipment. Production can be aligned with relevant standards such as FCC (Food Chemicals Codex) for food-grade applications or other industry-specific requirements upon request.

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). Due to its hygroscopic (moisture-sensitive) nature, the container must be kept tightly sealed after each use to prevent absorption of atmospheric moisture, which can affect performance.
