• Product Name: Silicon Dioxide
• Synonyms: Silica; Silicic acid anhydride; Fumed silica (for pyrogenic grade); Precipitated silica (for precipitated grade)
• Appearance: White amorphous powder; odorless, tasteless
• Grade Options: Food grade, Pharmaceutical grade, Industrial grade

• Food Industry: Anti-caking agent (E551) for powders, spices, and baking mixes; flow aid for food additives.
• Pharmaceutical Industry: Excipient for tablet formulations to improve flowability and compressibility; carrier for active pharmaceutical ingredients (APIs).
• Industrial & Chemical Industry: Reinforcing filler for rubber, plastics, and coatings; thickener for adhesives and sealants; abrasive in polishing agents.
• Cosmetics Industry: Matting agent in skincare and makeup products; absorbent in talcum powder and deodorants.

• Storage Conditions: Store in a cool, dry, well-ventilated warehouse; keep away from moisture, strong acids, and hydrofluoric acid. Seal the package tightly to prevent dust dispersion and caking.
• Handling Precautions: Wear dust-proof respirator, gloves, and goggles during operation. Avoid inhalation of dust, which may cause respiratory irritation. Clean up spilled powder promptly with a vacuum cleaner (avoid sweeping to prevent dust spread).

• Stability: Chemically stable under normal storage and use conditions; non-flammable, non-explosive.
• Incompatibility: Reacts with hydrofluoric acid to produce toxic silicon tetrafluoride gas; avoid contact with strong alkalis for long periods.
• Hazardous Decomposition Products: No hazardous decomposition products under normal use; may produce silicon oxide fumes at high temperatures (>1800 °C).

• Food Grade: Complies with FCC (Food Chemicals Codex), EU E551 standards.
• Pharmaceutical Grade: Meets USP (United States Pharmacopeia), EP (European Pharmacopoeia) specifications.
• Industrial Grade: Conforms to industry standards for rubber and plastic filler applications.

• Standard Packaging: 25 kg net weight in polyethylene-lined kraft paper bags or woven polypropylene bags; 1000 kg in bulk FIBC bags.
• Custom Packaging: 1 kg, 5 kg food/pharma-grade plastic bottles available for small-batch orders.

• Hazard Classification: Non-hazardous chemical (not regulated as dangerous goods for transportation).
• Transport Precautions: Prevent package breakage during transit; avoid mixing with hydrofluoric acid and strong acids. Protect from rain and moisture during transportation.

1. For reinforcement and thickening requirements (e.g., rubber, coatings), choose nano-scale fumed silica.
2. For food, pharmaceutical and cosmetic applications, prioritize 1–10 μm food/pharma grade precipitated silica to ensure compliance with safety standards.
3. For cost-sensitive industrial filling scenarios, 10–50 μm ground silica is the preferred economical option.
