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 99.8% purity colloidal silicon dioxide nano silica HB-630 nanoparticles sio2 hydrophobic fumed silica fumed

HB-630 is hydrophobic fumed silica. This product is an unique silica powder. It drives away water strongly. The particles are incredibly little, nano-sized. Their ordinary size is about 7 nanometers. This small size provides a significant surface area. The area mores than 600 square meters per gram. This huge surface area is crucial for its performance.

The pureness is extremely high. It is 99.8% pure silicon dioxide (SiO2). This high purity ensures consistent outcomes. It minimizes unwanted responses in your final product. The product looks like a fine, fluffy white powder. It is really light and moves easily.

This silica is made using a special fire procedure. This technique creates the nano-sized particles. After that, a therapy makes the surface area hydrophobic. This therapy stops water absorption. The powder remains completely dry and free-flowing. It mixes well right into several products without clumping.

HB-630 works well in several applications. It reinforces silicone rubber properly. It makes the rubber stronger. It thickens finishings, paints, and adhesives. It regulates how they move and resolve. It avoids settling of solids in liquids. It functions as an anti-settling agent. It improves the feeling and appearance of cosmetics. It offers a smooth, non-greasy surface. It strengthens plastic components. It makes plastics much more durable.

The hydrophobic nature is a huge advantage. It maintains the powder dry in humid conditions. This makes storage and handling simpler. It improves compatibility with non-polar materials. Think oils, materials, and several polymers. It disperses better in these systems. This leads to more uniform products. Performance is extra reputable.

You obtain a high-performance additive. It uses thickening, reinforcement, and anti-settling. It operates in demanding settings requiring water resistance. Its high purity and nano-size provide effective results at low use levels.

Applications of 99.8% purity colloidal silicon dioxide nano silica HB-630 nanoparticles sio2 hydrophobic fumed silica fumed

This is colloidal silicon dioxide nanoparticles called HB-630. It’s unbelievably pure, 99.8%. The particles are very small. They are hydrophobic, meaning they repel water. This is fumed silica, a details kind.

HB-630 is really beneficial in commercial finishings. Its water resistance is crucial. It quits water from harmful surface areas. This makes paints and varnishes last much longer. The little particles fill gaps well. This develops a smoother, stronger protective layer. It stops deterioration effectively.

It enhances plastics dramatically. Adding HB-630 makes plastic components more powerful. They stand up to breaking far better. The plastic additionally becomes even more rigid. This is good for parts requiring security. The hydrophobic nature reduces wetness absorption. Moisture compromises plastics over time. This assists avoid that.

HB-630 functions well in adhesives and sealers. It controls density. It quits the material from leaking or sagging. This makes application much easier. It likewise increases strength. Bonds hold tighter. The nanoparticles avoid clumping. This guarantees a smooth, regular mixture.

In paints and inks, HB-630 protects against resolving. Solid particles stay blended equally. This stays clear of separation in the canister. It gives a much better finish. The shade looks much more uniform. Brushing or splashing is smoother. The hydrophobic residential property assists. It makes the dried paint withstand water discolorations.

The pharmaceutical market makes use of HB-630. It functions as a circulation representative. Powdered medicines flow easily. This quickens capsule or tablet computer manufacturing. It avoids powders from adhering to makers. Uniformity is essential for precise dosing. This assists attain that.

Cosmetics profit too. HB-630 boosts structure in lotions and creams. It offers a silky feeling. It assists manage density. Products spread out conveniently without being drippy. It can additionally absorb excess oil. This is useful in make-up structures and powders.

5 FAQs of 99.8% purity colloidal silicon dioxide nano silica HB-630 nanoparticles sio2 hydrophobic fumed silica fumed

What exactly is HB-630?
HB-630 is a special kind of silica powder. It’s made of extremely tiny particles. We call it nano silica. The purity is 99.8%. It’s hydrophobic, meaning it repels water strongly. The particles are fumed silica, created through a high-temperature process. This gives them unique properties.

Why is the 99.8% purity important?
High purity matters a lot. It means almost no other materials are present. Impurities can affect performance negatively. This level ensures consistent, reliable results. It guarantees the silica behaves predictably in your applications. You get the exact performance you need.

What does ‘hydrophobic’ mean for this product?
Hydrophobic means water-hating. HB-630 particles actively repel water. They won’t absorb moisture from the air. This keeps them flowing freely. It prevents clumping. This feature is vital for uses where water causes problems, like in certain plastics or coatings.

How small are these nanoparticles?
These particles are extremely small. They are on the nanoscale. Think billionths of a meter. The primary particle size is very tiny. This huge surface area gives HB-630 its power. Small size allows it to mix thoroughly. It interacts effectively with other materials.
