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 Best Silica SiO2 Powder SSA 380 CAS No. 112945-52-5 Hydrophobic Fumed Silica

Top 5 FAQs About Hydrophobic Fumed Silica (SSA 380, CAS No. 112945-52-5)

What is hydrophobic fumed silica?

Hydrophobic fumed silica is a fine white powder made from silicon dioxide (SiO₂). It has been treated to repel water. This version has a specific surface area (SSA) of 380 m²/g and carries CAS number 112945-52-5. It is widely used as a thickener, anti-caking agent, or reinforcing filler.

How does it differ from regular fumed silica?

Regular fumed silica attracts moisture. Hydrophobic fumed silica has been surface-treated with chemicals like dimethyldichlorosilane. This treatment makes it water-repellent. As a result, it performs better in wet or humid environments.

Where is this silica commonly used?

This powder is used in coatings, adhesives, sealants, and cosmetics. It helps control flow, prevent settling, and improve texture. You’ll also find it in industrial lubricants, paints, and some food-grade applications where moisture resistance matters.

Is it safe to handle?

Yes, but take basic precautions. Avoid breathing the dust. Use gloves and eye protection when handling large amounts. Store it in a dry, sealed container away from moisture. Always follow the safety data sheet (SDS) guidelines.

Why choose SSA 380 grade?

The 380 m²/g surface area means very high reactivity and strong thickening power. This grade gives excellent performance in small doses. It mixes well into liquids and provides stable viscosity over time. That’s why many manufacturers prefer it for high-quality formulations.
