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 High Purity Fumed Silica Dioxide Nanoparticles Hydrophobic

This high purity fumed silica powder is hydrophobic. It pushes back water properly. The core product is silicon dioxide (SiO2). We produce it making use of a special fire process. This develops very tiny fragments. These fragments form complex chains and collections. This framework gives the powder one-of-a-kind homes.

The pureness level is remarkably high. It is 99.8% pure SiO2 minimum. This decreases unwanted contaminations. Such pureness is important for sensitive applications. Consistency is assured batch after set.

The hydrophobic nature is crucial. We deal with the silica surface with unique representatives. These agents connect completely to the silica. This develops a water-repelling layer. The powder won’t absorb dampness from the air. It remains free-flowing. It spreads conveniently right into natural products. Think plastics, materials, and rubbers. It doesn’t glob with each other.

Bit size is very small. The key particles procedure in between 7 and 40 nanometers. That’s incredibly little. The surface area is very large. Expect 150 to 300 square meters per gram. This huge surface drives performance. The powder serves as a powerful thickener. It strengthens materials. It manages viscosity well. It prevents resolving in fluids.

This hydrophobic fumed silica works in numerous systems. Utilize it in silicone rubber. It boosts stamina and processing. Add it to finishes and paints. It controls circulation and prevents sagging. Place it in adhesives and sealers. It adjusts density and avoids trickling. Include it in gel coats and unsaturated polyester materials. It protects against separation and includes body. Use it in publishing inks. It modifies rheology. Attempt it in cosmetics and personal care products. It offers appearance and security. It functions well with non-polar liquids. It boosts efficiency popular conditions. The powder is chemically steady. It manages warm up to heats accurately.

Applications of High Purity Fumed Silica Dioxide Nanoparticles Hydrophobic

High pureness hydrophobic fumed silica dioxide nanoparticles are really beneficial. They ward off water strongly. This quits water from adhering to them or getting inside materials. This special powder finds several vital jobs.

In paints and coatings, adding this silica makes surface areas waterproof. Rainfall slides straight off. It also quits dust from accumulating. This maintains structures and automobiles cleaner much longer. The paint remains looking great. The particles help the paint flow smoothly onto surface areas. They protect against drips and runs.

Plastics benefit a lot. Mixing this silica into plastics makes them stronger and stiffer. It also maintains them from taking in water. This is key for parts used outdoors or in damp places. Electronic devices need this protection. The plastic remains steady and lasts longer.

Rubber products like seals and gaskets utilize this silica also. It makes the rubber harder and much more resistant to tearing. The rubber additionally takes care of warmth better. This is important for auto parts under the hood. The seals last much longer and function much better.

Adhesives and sealers get improved. The silica enlarges them without adding much weight. This helps the glue keep where you place it. It doesn’t depression or drip. The final bond is stronger and extra dependable. Water can not quickly simplify.

Cosmetics and individual treatment things utilize this powder. It makes lotions and creams feel smooth. It quits powders like structure from clumping. The item spreads conveniently on your skin. It gives a wonderful, even complete.

In food and pharmaceuticals, it serves as a flow help. It stops powders like flavors or medicine ingredients from sticking. This maintains them free-flowing in the manufacturing facility. Manufacturing is easier and much faster. It makes certain constant blending and filling up.

5 FAQs of High Purity Fumed Silica Dioxide Nanoparticles Hydrophobic

What are hydrophobic fumed silica nanoparticles?
These are tiny particles of silicon dioxide. They are made in a flame. This process creates very high surface area. They are treated to repel water. This makes them hydrophobic. The particle size is extremely small, in the nanometers.

Why make fumed silica hydrophobic?
Repelling water is crucial for many uses. Hydrophobic silica mixes better with oils and plastics. It avoids clumping in moist air. This stability is key for performance. Hydrophilic silica attracts water and can gel.

Where is hydrophobic fumed silica used?
It serves many industries. Silicone sealants and rubbers use it for reinforcement. Coatings and inks add it for better flow and matting effects. Adhesives benefit from its thickening power. Plastics gain improved processing. Personal care products like powders use it too.

Is hydrophobic fumed silica safe to handle?
Handle it carefully. The fine powder can be dusty. Avoid breathing the dust. Use proper ventilation. Wear protective gloves and a dust mask. Keep containers sealed tight. Follow the supplier’s safety data sheet exactly.

What benefits does it offer over other additives?
It provides strong thickening with less material. It controls flow very effectively. It prevents settling in liquids. It reinforces materials without adding much weight. Its water-repellent nature keeps products stable in humid conditions.
