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.

The product has at the very least 99.8% SiO ₂. Its particular area usually ranges from 50 to 400 m ²/ g, depending upon the quality. The mass thickness is low, normally in between 30 and 80 g/L. Fumed silica is insoluble in water and most organic solvents. It reveals exceptional thermal security and remains chemically inert under typical conditions.

Typical Applications

This silica is commonly made use of as a thickening representative, anti-caking additive, or strengthening filler. In paints and coverings, it helps protect against pigment settling and enhances scratch resistance. In adhesives and sealants, it manages circulation and quits drooping. Rubber and plastic producers include it to increase mechanical strength. It also functions well in cosmetics, pharmaceuticals, and food-grade items where pureness matters.

Handling and Storage

Shop fumed silica in a dry, amazing area away from dampness. Maintain containers tightly closed when not in use. Though it is not categorized as unsafe, avoid breathing dust throughout handling. Use correct air flow and wear safety gear like gloves and a mask if operating in confined locations. Do not combine with strong antacid or hydrofluoric acid.

Packaging Choices

The item is available in multi-wall paper bags lined with polyethylene, commonly 10 kg or 20 kg per bag. Bulk product packaging in extremely sacks (500– 1000 kg) is additionally offered upon request. All bundles are identified plainly with item name, CAS number, batch code, and safety and security information.

Applications of 14808-60-7 FUMED SILICA Precipitated Silica Pure Sio2 Silicon Dioxide

Applications of Fumed Silica (CAS 14808-60-7)

Thickening and Anti-Settling Agent

Fumed silica is commonly utilized to thicken fluids and protect against strong fragments from resolving. It works well in paints, finishings, adhesives, and sealants. When added in percentages, it gives these items a stable structure without changing their color or quality.

Rheology Control in Industrial Products

This pure SiO two powder assists control how liquids circulation. In inks and materials, it stops leaking and sagging during application. That makes the last finish smooth and even. Its fine bit size allows easy blending and consistent efficiency.

Reinforcement in Rubber and Plastics

Makers add fumed silica to rubber and plastic compounds to improve toughness and sturdiness. It increases tear resistance and expands product life. Tires, hoses, and commercial belts frequently have this additive for far better mechanical residential or commercial properties.

Free-Flow Aid in Powders

In food-grade and pharmaceutical powders, fumed silica maintains ingredients from clumping. It makes certain smooth putting and exact dosing. Due to the fact that it is chemically inert and pure, it satisfies strict security requirements for human usage.

Matting Agent in Coatings

For a soft, non-glossy surface, fumed silica is used in timber surfaces, vehicle paints, and printing inks. It scatters light evenly to create an uniform matte look without damaging the coating’s safety top qualities.

Efficiency Enhancer in Cosmetics

Makeup and skincare products make use of fumed silica to take in oil, enhance spreadability, and provide a silky feel. It aids powders remain on the skin much longer and reduces shine. Its ultra-fine nature makes it comfortable to wear.

Fumed silica (CAS 14808-60-7) is valued for its high purity, regular top quality, and convenience. Whether in building, electronic devices, or personal care, it addresses usual formula challenges with straightforward, trustworthy results.

5 FAQs of 14808-60-7 FUMED SILICA Precipitated Silica Pure Sio2 Silicon Dioxide

Frequently Asked Questions About Fumed Silica (CAS 14808-60-7)

What is fumed silica?

Fumed silica is a very fine powder made of pure silicon dioxide (SiO₂). It is created through a high-temperature process that produces tiny, chain-like particles. This gives it strong thickening and anti-caking properties. People also call it pyrogenic silica.

How is fumed silica different from precipitated silica?

Both are forms of silicon dioxide, but they are made in different ways. Fumed silica is made by burning silicon tetrachloride in a flame. Precipitated silica comes from a wet chemical process using silicate salts. Fumed silica has smaller particles, higher surface area, and better performance in thickening and reinforcing.

What is fumed silica used for?

It is used in many industries. In paints and coatings, it stops sagging and settling. In adhesives and sealants, it controls flow and improves strength. It also works as a free-flow agent in powders like spices or pharmaceuticals. Some cosmetics and food products use it too, but only if it meets safety standards.

Is fumed silica safe to handle?

In solid form, it is not highly toxic. But breathing in the fine dust can irritate your lungs. Always wear a mask, gloves, and eye protection when handling it. Keep it away from open flames—it does not burn, but dust clouds can be explosive under certain conditions.

How should I store fumed silica?

Store it in a dry, cool place inside a sealed container. Moisture makes it clump together, which lowers its effectiveness. Keep the bag or drum closed when not in use. Label the container clearly and follow local safety rules for storage.
