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 White SiO2 Fumed Silica 99% SiO2 Content Fine White Fumed Silica Powder For Rubber

Frequently Asked Questions About White SiO2 Fumed Silica

What is white fumed silica?

White fumed silica is a very fine powder made of silicon dioxide (SiO₂). It has a purity of 99% SiO₂. The powder is produced through a high-temperature process that creates tiny particles with a large surface area. This gives it strong thickening and reinforcing abilities.

How does it help rubber products?

This silica improves the strength and durability of rubber. It makes rubber more resistant to tearing and wear. It also helps control how thick or thin the rubber compound is during processing. Many manufacturers use it in tires, seals, hoses, and other rubber parts to get better performance.

Is it safe to handle?

Yes, but you must follow basic safety steps. The powder is not toxic, but breathing in fine dust can irritate your lungs. Always wear a mask, gloves, and eye protection when handling it. Keep the work area well ventilated and avoid creating dust clouds.

How should I store fumed silica?

Store it in a dry, cool place inside sealed containers. Moisture can cause the powder to clump together, which makes it harder to mix evenly into rubber. Keep it away from water, steam, and high humidity. Use clean, dry tools when scooping the material.

Can it be mixed easily into rubber?

Yes, but good mixing is key. Because the particles are so fine, they tend to stick together. Use proper mixing equipment like internal mixers or two-roll mills. Add the silica slowly while mixing to avoid lumps. This ensures even distribution and full benefit in the final rubber product.
