Description

Silica CAS NO 14464-46-1 is a high-purity, amorphous silicon dioxide powder, a fundamental inorganic compound with extensive industrial utility. Its exceptional chemical inertness, high surface area, and tunable particle size make it a critical performance additive and processing aid. This material is essential for manufacturers in sectors requiring precise control over rheology, reinforcement, adsorption, and thermal stability. Key industries that rely on this product include pharmaceuticals, food technology, electronics, and advanced composites.

Application

• Pharmaceuticals: Used as a glidant and anti-caking agent in tablet formulations, a thickening agent in semi-solid preparations, and a carrier for active ingredients.
• Food & Beverage: Functions as an anti-caking agent in powdered foods (e.g., spices, drink mixes), a clarifier in beer and wine, and a viscosity control agent.
• Industrial Coatings & Adhesives: Acts as a rheology modifier and anti-settling agent to improve shelf stability and application properties of paints, sealants, and adhesives.
• Electronics & Optics: Serves as a filler in epoxy molding compounds for semiconductors and as a raw material for producing high-purity quartz glass and optical fibers.
• Personal Care & Cosmetics: Employed as an absorbent, viscosity enhancer, and mild abrasive in products like toothpaste, facial scrubs, and powders.
• Rubber & Elastomers: Provides reinforcement, improving tensile strength, tear resistance, and abrasion properties in silicone rubber and other elastomeric products.
• Catalyst & Chemical Synthesis: Used as a catalyst support and as a drying agent due to its high adsorption capacity and thermal stability.
• Construction Materials: Incorporated into cement and concrete mixtures to improve compressive strength and durability.

Quality Control

Our Silica is produced and tested under a stringent quality management system to ensure batch-to-batch consistency and compliance with relevant industry standards, including USP-NF, FCC, and REACH. Each production lot undergoes comprehensive analysis for critical parameters such as purity, particle size distribution, loss on drying, and heavy metal content. A Certificate of Analysis (COA) documenting these results is provided with every shipment to guarantee product integrity and support your quality assurance protocols.

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). This material is hygroscopic (moisture-sensitive); keep the container tightly sealed when not in use to prevent moisture absorption and caking. Keep away from strong acids and strong bases.
