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.

Applications of SiO2.x(H2O) white carbon black cas 10279-57-9 hydrophobic fumed silica

Hydrophobic fumed silica is a special kind of white carbon black. Its chemical name is SiO2.x(WATER). You recognize it by CAS number 10279-57-9. This product is dealt with to resist water. Normal silica attracts water. This dealt with version pushes water away. That modification makes it very beneficial in several items.

It works as an effective thickener. You include a bit. It makes liquids thicker. Think of paints or finishes. It helps them stay on a surface area without leaking. This silica makes the paint smooth and easy to apply. It prevents sagging on upright wall surfaces. Sealers and adhesives also utilize it. Silicone sealers require it. The silica makes the paste thick and secure. It stops the sealant from penetrating spaces prior to it establishes.

This silica is excellent for enhancing products. It makes silicone rubber more powerful. The rubber obtains far better tear resistance. It likewise manages heat better. Plastics profit as well. Including hydrophobic fumed silica makes plastics stiffer. It improves their resistance to put on.

Since it despises water, it’s ideal for waterproofing. It assists keep moisture out of systems. Electric elements occasionally utilize it. It keeps insulation completely dry and safe. Powders need anti-caking help. Hydrophobic fumed silica does this job well. It coats powder particles. This quits them sticking when damp. You see this in food powders or building and construction materials like cement.

Cosmetics count on its homes. It makes creams really feel silky. It controls shine in make-up. Lipsticks utilize it for structure. It helps pigments spread uniformly. It also stops shades from blood loss. Industrial coverings use it for longevity. The silica helps the finish stand up to weather condition and chemicals. It makes surface areas less complicated to clean also. Its tiny fragment dimension fills little spaces. This creates a smoother, harder finish.

5 FAQs of SiO2.x(H2O) white carbon black cas 10279-57-9 hydrophobic fumed silica

Here are 5 common questions about our hydrophobic fumed silica, SiO₂·x(H₂O), CAS 10279-57-9:

What is hydrophobic fumed silica? This is a special white powder. It’s made from silicon dioxide treated to repel water. The treatment makes it dislike water molecules. This property is key for its uses.

Is it safe to handle? Yes, with proper care. Handle it like any fine powder. Avoid breathing the dust. Wear gloves and safety glasses. Use it in well-ventilated areas. Refer to the Safety Data Sheet for full details. Follow the handling instructions.

What does it do in products? It acts mainly as a thickener and a flow aid. It prevents settling in liquids. It controls viscosity in coatings and adhesives. It makes powders flow freely. It reinforces silicone rubber. Its water-repellency is crucial for these jobs.

Can I mix it with water-based systems? No, generally not. Its core feature is repelling water. Adding it directly to water usually causes clumping. It works best in oils, solvents, and silicone polymers. Some special processes might incorporate it, but direct mixing fails.

How long does it last? It has a long shelf life. Store it properly. Keep it in a cool, dry place. Keep the container tightly sealed. Protect it from moisture. Avoid extreme heat. Stored correctly, it remains effective for years. Check the container for the specific expiration date.
