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 Whole nano SiO2 silicon dioxide hydrophobic fumed silica silica nanoparticles

Our hydrophobic fumed silica nanoparticles are pure silicon dioxide (SiO2). They are unbelievably little. We make them using a special fire process. This process gives them distinct homes. We deal with the surface area to make them fend off water. That’s the hydrophobic component. This treatment is key for lots of usages.

The bits themselves are nano-sized. Think of sizes around 7 to 40 nanometers. These tiny particles team together. They develop bigger frameworks called aggregates. The accumulations form even bigger collections. This framework provides a big surface. Surface areas are really high, frequently 100 to 400 square meters per gram. This huge area enables strong interactions with other products.

The hydrophobicity degree is vital. It tells us exactly how well the silica repels water. We measure it by just how much silanol groups are covered on the surface. Greater coverage indicates much better water resistance. You need the ideal degree for your details application. We provide various qualities. Each quality has a specified hydrophobicity.

Pureness is vital. Our product is over 99.8% pure SiO2. This high pureness makes certain constant performance. It prevents undesirable responses in sensitive mixtures. The bulk density is reduced. It varies from regarding 30 to 50 grams per liter. This low thickness makes it easy to manage. It helps dispersion right into fluids.

The pH worth matters also. It usually falls between 3.5 and 5.5. This slightly acidic nature is essential for stability. It impacts just how the silica acts in various systems. The powder flows conveniently. Its physical type is a fine, white powder. It feels smooth.

These specs interact. They make our hydrophobic fumed silica extremely reliable. It strengthens products. It works as a thickener. It protects against working out. It helps control circulation. It boosts toughness. It functions well in layers, adhesives, sealers, plastics, and materials. Select the right grade based upon bit dimension, surface, and hydrophobicity.

Applications of Whole nano SiO2 silicon dioxide hydrophobic fumed silica silica nanoparticles

Hydrophobic fumed silica nanoparticles are little bits of silicon dioxide. They are dealt with to fend off water. This makes them very useful in several products. These particles boost just how things function. They aid enlarge liquids. They make products stronger. They also make surface areas resist water far better.

One huge use remains in paints and coverings. Adding these nanoparticles makes the paint thicker. This assists it stick much better. It additionally quits water from taking in. So surface areas stay dry longer. The paint lasts longer too. This benefits outside buildings and automobiles.

These particles are essential in adhesives and sealers. They manage just how thick the glue is. This makes it much easier to apply. The glue holds points with each other strongly. It also doesn’t run or drip much. Sealers remain versatile and maintain water out well.

Plastics and rubber items improve with these nanoparticles. They make the product tougher. The material does not damage as conveniently. It likewise does not damage as swiftly. Tires and shoe soles utilize them. This helps the items last longer.

Personal treatment items like lotions use them also. They make lotions feel smooth. They stop the cream from separating. The cream spreads conveniently on skin. This makes the product nicer to use.

Printing inks function better with these bits. The ink flows well. It dries out swiftly on paper. The print looks sharp. It also sticks to the paper strongly. This is good for high-grade printing.

These nanoparticles aid make batteries and solar batteries. They improve exactly how power flows inside them. This can make the devices work much better. They might last longer as well. Research is recurring below.

Powdered chemicals and foods use these fragments. They stop the powder from clumping. The powder flows openly. It blends quickly with various other things. This makes managing powders simpler.

5 FAQs of Whole nano SiO2 silicon dioxide hydrophobic fumed silica silica nanoparticles

Here are five common questions about hydrophobic fumed silica nanoparticles:

What are hydrophobic fumed silica nanoparticles?
They are tiny particles made mostly of silicon dioxide. Manufacturers make them in a special high-temperature flame process. This process creates particles with very small size and high surface area. A chemical treatment makes their surface repel water. This treatment gives them their hydrophobic property.

How does the hydrophobic surface work?
A special substance coats the particle surface during production. This coating has non-polar groups. Water molecules are polar. Non-polar and polar substances do not mix well. The coating stops water from sticking to the silica particles. The particles stay dry and flow freely.

Where are these nanoparticles used?
Their main job is to thicken liquids and make powders flow better. They work well in silicone sealants and adhesives. Paint and coating formulators add them to stop settling and improve application. They act as anti-caking agents in powdered foods and industrial powders. Their water-repelling nature is key in waterproof coatings.

Are they safe to handle?
Handle them carefully like any fine powder. Avoid breathing in the dust. Use protective equipment like masks and gloves. Good ventilation in the work area is important. Follow the safety instructions on the product’s Material Safety Data Sheet (MSDS). Store them away from moisture in a sealed container.

How much should I add to my product?
The right amount depends on your specific material. Start with a small percentage. Test different loading levels. You want enough to get the thickening or anti-settling effect you need. Too much can make your mixture too thick or change other properties. Small trial batches help find the best amount.
