Overview of Fumed Silica

Fumed silica, also known as pyrogenic silica, is an ultra-fine, high-purity amorphous silicon dioxide (SiO2) produced via the combustion of silicon tetrachloride in an oxygen-hydrogen flame. It appears as a fluffy white powder and is valued for its ability to thicken, stabilize, and reinforce materials.

Features of Fumed Silica

• High Surface Area: Typically ranges from 50 to 380 m²/g, providing excellent thickening and reinforcing properties.
• Hydrophilic or Hydrophobic Variants: Available in both forms depending on surface treatment, allowing for tailored applications.
• Excellent Thixotropy: Increases viscosity and improves flow properties of liquids and pastes.
• Chemical Inertness: Resistant to most chemicals, making it suitable for a wide range of industrial uses.

•  Enhances free-flowing properties and stability.

5 FAQs of High-Purity Hydrophilic Fumed Silica Thickener Domestic Powder 25kg MOQ

What is high-purity hydrophilic fumed silica thickener? High-purity hydrophilic fumed silica thickener is a synthetic, nano-sized silicon dioxide powder produced through vapor-phase hydrolysis. It acts as a thickening, anti-settling, and rheology-control agent in liquid systems. Its hydrophilic surface allows strong interaction with polar liquids like water, enhancing viscosity, stability, and texture in formulations. Applications include coatings, adhesives, sealants, cosmetics, and pharmaceuticals, where precise thickening and flow control are critical.

Which industries commonly use this product? This product is widely used in coatings and paints, adhesives, construction materials, pharmaceuticals, cosmetics, and food-grade applications. It improves texture in gels, stabilizes suspensions in inks, prevents sagging in adhesives, and enhances drug tablet compaction. Its high purity makes it suitable for sensitive applications like medical gels or food additives, where contaminants must be minimized.

Why is the MOQ set at 25kg? The 25kg minimum order quantity (MOQ) balances cost-efficiency for both suppliers and buyers. Bulk packaging reduces per-unit production and shipping costs, making it ideal for industrial clients or manufacturers requiring consistent supply for large-scale production. Smaller quantities may not justify logistical or handling expenses, though custom orders can sometimes be negotiated.

How does the hydrophilic nature impact performance? The hydrophilic surface contains silanol groups that bond with water and polar solvents, creating hydrogen bonds that thicken liquids. This improves suspension stability, prevents sedimentation, and ensures even dispersion. It’s ideal for water-based systems, offering better compatibility than hydrophobic variants, which are suited for non-polar solvents.

What are the storage and handling guidelines? Store in a cool, dry place at 15–25°C, sealed in original moisture-resistant packaging. Avoid humidity to prevent clumping. Use non-reactive containers if transferring. Handle with protective gear to avoid inhalation or contact. Shelf life is typically 12–24 months if stored properly. Do not expose to extreme temperatures or direct sunlight.
