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.

High-Purity Fumed Nano Silica: A Key Component for Advanced Rubber Efficiency

What It Is

This item is fumed nano silica with bit dimensions between 50 and 60 nanometers. It has a pureness degree of 99.8% and appears as a great white powder. Additionally known as white carbon black or pyrogenic silica (CAS No. 7631-86-9), it is made via a high-temperature vapor-phase procedure that guarantees regular quality and efficiency.

Why It Matters in Rubber

Rubber items typically need added strength, toughness, and resistance to put on. Adding this fumed nano silica provides rubber those top qualities. The small bits mix equally into rubber compounds. They form solid networks inside the material. This enhances tensile stamina, tear resistance, and abrasion resistance.

How It Works

As a result of its high area and reactive silanol teams, the silica bonds well with rubber polymers. This enhances the general structure of the rubber. It also helps control viscosity during handling. That implies easier mixing, far better circulation, and a lot more consistent treating. The outcome is a smoother manufacturing procedure and higher-quality output.

Where It’s Made use of

Producers use this silica in many rubber-based items. Usual applications consist of automotive tires, seals, tubes, belts, and industrial rollers. It is particularly important in high-performance tires where grasp, rolling resistance, and durability are critical. The silica additionally sustains green tire designs by decreasing fuel intake through reduced warm build-up.

Quality You Can Depend On

5 FAQs of fumed nano silica 50-60 nm SiO2 high purity 99.8% white carbon black pyrogenic silica 7631-86-9 rubber-strengthening agent

Frequently Asked Questions About Fumed Nano Silica (50–60 nm, 99.8% Purity)

What is fumed nano silica?

Fumed nano silica is a very fine white powder made from silicon dioxide (SiO₂). It has particle sizes between 50 and 60 nanometers. This material is also called pyrogenic silica or white carbon black. Its CAS number is 7631-86-9. The purity level is 99.8%, which makes it suitable for high-performance applications.

How is it produced?

It is made through a high-temperature flame hydrolysis process. Silicon tetrachloride vapor reacts with oxygen and hydrogen in a flame. This creates pure SiO₂ nanoparticles that fuse into chain-like structures. The result is a lightweight, fluffy powder with high surface area and strong thickening ability.

Why use it in rubber?

This silica greatly improves rubber strength. It boosts tear resistance, abrasion resistance, and tensile strength. It also helps rubber keep its shape under stress. Because of its nano size and high purity, it mixes well into rubber compounds without clumping.

Is it safe to handle?

Yes, but basic safety steps are needed. Wear gloves, eye protection, and a dust mask when handling the powder. It is not toxic, but fine dust can irritate the lungs or eyes if inhaled or contacted directly. Store it in a dry, sealed container away from moisture.

What industries use this product?

It is widely used in rubber manufacturing, especially for tires and industrial seals. It also appears in adhesives, coatings, cosmetics, and electronics. Any field needing reinforcement, anti-settling, or thickening benefits can use this high-purity fumed silica.
