Product Review

Fumed silicon dioxide is a high-purity nano-sized silica made via flame hydrolysis. It looks like a fine, free-flowing white powder. This product is extensively used as a thickening agent, anti-caking additive, and reinforcing filler in many industrial and consumer items.

Secret Features

The key component is amorphous silicon dioxide (SiO ₂), with pureness degrees usually over 99.8%. Particle dimension ranges from 5 to 50 nanometers, offering it a really high area– generally in between 50 and 400 m ²/ g. These small bits create loosened agglomerates that quickly disintegrate during blending, ensuring also dispersion.

2 major types are available: hydrophilic and hydrophobic .
– Hydrophilic fumed silica has surface silanol (Si-OH) teams. It mixes well with water and polar liquids.
– Hydrophobic fumed silica is treated with organosilanes or chlorosilanes. This alters its surface area chemistry so it repels water and functions much better in non-polar systems like oils and solvents.

Technical Specs

– Chemical formula : SiO ₂.
– Look : White, cosy powder.
– Loss on drying : ≤ 1.5% at 105 ° C for 2 hours.
– Ignition loss : ≤ 5.0% at 1000 ° C.
– pH worth (in 4% suspension): 3.6– 4.8 (hydrophilic); varies for hydrophobic qualities.
– Mass thickness : 30– 80 g/L.
– Real density : ~ 2.2 g/cm FIVE.

Typical Applications

This product is utilized in paints, coverings, adhesives, sealers, cosmetics, drugs, preservative, and rubber compounds. In liquid systems, it stops settling and manages circulation. In powders, it quits clumping and enhances pourability. Its performance relies on picking the right quality– hydrophilic for water-based systems, hydrophobic for oil-based or moisture-sensitive applications.

Applications of Fumed Silicon Dioxide

Versatile Performance in Industrial Formulations

Fumed silicon dioxide, additionally called fumed silica or colloidal nano silica, is widely utilized throughout lots of markets. It can be found in two major kinds: hydrophobic and hydrophilic. Each kind offers various needs based upon how it connects with water.

The hydrophilic create blends well with water and polar materials. It works as a thickening representative, anti-settling aid, and free-flow additive. Paints, finishings, adhesives, and sealants utilize it to manage thickness and avoid pigments from sinking. In cosmetics like powders and creams, it boosts texture and aids items spread out equally.

The hydrophobic variation drives away water. This makes it optimal for moisture-sensitive applications. It is included in commercial lubricants, greases, and resins to enhance stability and avoid clumping. In construction products such as concrete and cements, it improves flow without adding additional water. It likewise helps maintain powdered chemicals dry throughout storage space and transport.

Both forms serve as enhancing fillers in silicone rubbers and elastomers. They boost tensile strength and enhance tear resistance. In drugs, fumed silica ensures uniform blending of energetic ingredients and keeps tablets from sticking during manufacturing.

Its ultrafine bit dimension and high surface area provide fumed silica distinct residential properties. These include excellent dispersion, solid thixotropy, and lasting security in complicated mixes. Producers count on it to solve solution challenges without transforming core ingredients.

Whether you need much better flow, stronger framework, or moisture control, fumed silicon dioxide provides regular results. Its flexibility makes it a go-to additive for high-performance items sought after environments.

5 FAQs of Fumed Silicon Dioxide Colloidal Nano Silica Hydrophobic Hydrophilic SiO2 Fumed Silica

Frequently Asked Questions About Fumed Silica

What is fumed silica?

Fumed silica is a very fine powder made from silicon dioxide (SiO₂). It forms through a high-temperature process that creates tiny, chain-like particles. These particles give the material special thickening and anti-caking properties. People use it in many products like paints, adhesives, cosmetics, and food.

What’s the difference between hydrophobic and hydrophilic fumed silica?

Hydrophilic fumed silica attracts water. It mixes well in water-based systems. Hydrophobic fumed silica repels water. Manufacturers treat it with special chemicals so it works better in oils or non-water environments. Pick one based on your product’s base—water or oil.

Why use nano-sized fumed silica?

Nano-sized particles have a huge surface area compared to their weight. This means even a small amount can greatly affect texture, stability, or flow. In coatings or sealants, it helps prevent sagging. In powders, it stops clumping. The small size also keeps the final product clear or smooth.

Is fumed silica safe to handle?

Fumed silica is generally safe when used correctly. But its fine dust can irritate eyes, skin, or lungs. Always wear gloves, goggles, and a mask when handling large amounts. Keep work areas clean and well-ventilated. Follow safety instructions on the product label.

How do I mix fumed silica into my product?

Add fumed silica slowly while stirring. High-shear mixing works best to break up clumps and spread particles evenly. For hydrophilic types, mix into water-based liquids first. For hydrophobic types, add to oils or solvents. Too much can make the mixture too thick, so start with a small dose and test results.
