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.

Specification of White SiO2 fumed silica 99% SiO2 content fine white fumed silica precipitated silica powder white carbon black for rubber

White SiO2 fumed silica has 99% SiO2 content. This makes it very pure. It is a fine white powder. People also call it precipitated silica or white carbon black. It is useful for rubber products. The particles are tiny. They have a high surface area. This surface area gives it special properties. It acts like a reinforcing agent. This means it makes rubber stronger. It helps rubber resist tearing better. It also improves the rubber’s abrasion resistance. So the rubber lasts longer when rubbed or worn down. The silica helps rubber hold its shape. It reduces how much the rubber stretches permanently. This is good for things like seals or gaskets. It helps mix the rubber ingredients evenly. The silica powder flows well. This makes it easy to handle in factories. It disperses smoothly into the rubber mix. The silica works well with many types of rubber. This includes natural rubber and synthetic rubbers. It helps improve the processing of rubber compounds. The final rubber products have a nicer surface finish. They look better. The silica also helps the rubber resist heat better. This is important for tires or engine parts. It makes the rubber perform well under pressure. The silica filler makes tires grip the road well. It also helps tires use less fuel. The powder is very white. It does not add color to the rubber. Manufacturers trust this material. It improves the quality of their rubber goods.

Applications of White SiO2 fumed silica 99% SiO2 content fine white fumed silica precipitated silica powder white carbon black for rubber

This white fumed silica powder contains 99% SiO2. It is a very fine material. It acts as a powerful reinforcing filler for rubber products. Manufacturers use it widely. It improves rubber strength significantly. Rubber parts last longer. It increases tensile strength. It boosts tear resistance too. The rubber becomes harder to break. Abrasion resistance gets much better. Rubber components wear down slower. This silica helps rubber hold its shape. It reduces permanent deformation. Rubber items return to their original form after stress. Processing is easier with this silica. It makes rubber mixtures flow smoother during production. Workers find it simpler to handle. The silica works well in the vulcanization process. Vulcanization makes rubber strong and elastic. It helps create a strong network inside the rubber. Silica improves grip for rubber surfaces. This is vital for safety. Tires need good traction. Shoe soles require it too. Different industries rely on this silica. Tire manufacturing uses a lot. It makes high-performance tires. Industrial rubber goods need it. These include hoses, belts, and seals. Footwear production uses silica. It strengthens shoe soles and parts. Silica makes rubber products more durable. They withstand harsh conditions better. This leads to longer product life. Cost-effectiveness improves for manufacturers. It replaces carbon black in white or colored rubbers. The result is bright, clean-looking products. Precipitated silica offers similar benefits. Both types are essential for quality rubber. They are known as white carbon black. Their performance is proven.

5 FAQs of White SiO2 fumed silica 99% SiO2 content fine white fumed silica precipitated silica powder white carbon black for rubber

White SiO2 fumed silica is a fine white powder. It has 99% SiO2 content. People also call it precipitated silica powder or white carbon black. It’s used a lot in rubber products. Here are common questions people ask.

What is White SiO2 fumed silica?
White SiO2 fumed silica is a very pure silicon dioxide powder. It is very fine and white. It’s made through a special high-temperature process. This process creates tiny particles. These particles have a big surface area. This makes them useful for many things.

Where is this silica powder used?
This powder is used mostly in rubber manufacturing. It acts as a reinforcing filler. It makes rubber stronger and more durable. It is also used in other industries. These include paints, coatings, adhesives, and sealants. It helps control thickness and flow.

How does it improve rubber?
Adding this silica makes rubber much tougher. It improves tear resistance. It also makes rubber more resistant to wear. The rubber becomes harder to cut or damage. It improves the rubber’s tensile strength. This means the rubber can stretch more before breaking. It also helps the rubber last longer.

Is it safe to handle?
Yes, but normal safety steps are needed. Wear a dust mask to avoid breathing it in. Use gloves to prevent skin contact. Keep it away from your eyes. Work in a well-ventilated area. Follow the safety instructions provided by the supplier.

How is it different from carbon black?
Carbon black is black and makes products dark. White SiO2 fumed silica is white. It lets you make light-colored or clear rubber goods. Both materials make rubber stronger. But silica gives different properties sometimes. Silica might offer better bonding with the rubber. This can improve performance.
