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 hydrophobic nano silica powder Hydrophobic Fumed Silica

This high purity hydrophobic nano silica powder is hydrophobic fumed silica. It is a very fine white powder. The particles are incredibly small, measured in nanometers. It feels light and fluffy. This material strongly repels water. Water forms beads on its surface instead of soaking in. The powder flows easily and resists clumping. This is due to its special surface treatment. The treatment makes it non-absorbent. It acts like a thickener or anti-settling agent in many liquids. It improves the texture and stability of coatings and paints. It prevents sagging. It stops fillers from sinking to the bottom. The powder reinforces silicone rubbers effectively. It makes them stronger and last longer. It works well in adhesives and sealants. It controls viscosity and prevents dripping. It is chemically inert. It does not react easily with other substances. This makes it safe for many uses. It offers excellent thermal stability. It performs well even at high temperatures. The powder is very pure. It contains very low levels of impurities. This purity is crucial for sensitive applications. It ensures consistent performance. Handling is straightforward because it flows freely. It mixes evenly into different materials. It helps create smooth, uniform products. Its tiny particle size provides a large surface area. This large area enhances its effectiveness as an additive. The hydrophobic nature keeps moisture out. This protects sensitive components. It extends the shelf life of many formulations. Use it for high-performance results.

5 FAQs of High Purity hydrophobic nano silica powder Hydrophobic Fumed Silica

Hydrophobic fumed silica powder is a special kind of silica. It repels water. Its surface is treated to be non-wet. This treatment makes it very different from normal silica. This powder is extremely pure. It is made using a specific flame process. This process gives it very fine particles. These particles have a large surface area. They are also very light.

Where is hydrophobic fumed silica powder used? It has many applications. It is common in silicone rubber products. Here it acts as a thickener. It makes the rubber stronger. It also improves how the rubber flows. You find it in paints and coatings too. It helps prevent settling. It makes the paint flow better. It is used in adhesives and sealants. There it controls thickness. It stops the material from sagging. It is also added to plastic compounds. It helps make processing easier. It improves the final product’s strength.

How should we handle this powder? Care is important. It is a very fine dust. This means it can float in the air easily. Always use proper ventilation. Wear a dust mask. Wear safety glasses too. Gloves are also recommended. Avoid breathing in the dust. Avoid getting it in your eyes. Store it in a cool, dry place. Keep the container tightly closed. This stops moisture getting in. Moisture can ruin its hydrophobic nature.

Is hydrophobic fumed silica powder safe? It is generally safe when handled correctly. Follow the safety instructions on the label. Do not breathe in the dust. Do not let it touch your skin often. Do not get it in your eyes. If you do get some in your eyes, rinse them with water immediately. If you breathe in a lot of dust, get fresh air quickly. If skin contact happens, wash the area with soap and water. Always read the Safety Data Sheet. The SDS has all the detailed safety information.

Why pick hydrophobic fumed silica powder over other powders? Its water-repelling nature is key. Normal silica absorbs water. This can cause problems in many products. Hydrophobic silica avoids these moisture issues. It offers better thickening power. It improves reinforcement in materials. It helps things flow smoothly during processing. Its high purity means fewer impurities. This leads to more consistent results. For applications needing water resistance, it is often the best choice.
