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.

Applications of Cheap Hydrophilic and hydrophobic fumed silica dioxide 90%-99% SiO2 content fine white fumed precipitated silica powder

Applications of High-Purity Fumed Silica Powder

This fine white powder consists of 90% to 99% SiO₂. It is available in both hydrophilic and hydrophobic types. Each kind functions well in various sectors because of exactly how it responds with water.

Hydrophilic Fumed Silica Uses

Hydrophilic silica enjoys water. It blends conveniently into fluids which contain water. This makes it valuable in paints, coverings, and adhesives. It stops pigments from sinking and helps maintain the mix secure gradually. In cosmetics like lotions and creams, it provides a smooth feel and improves texture. It additionally works in food-grade products as an anti-caking representative. Several pharmaceutical tablets use it to move far better during production.

Hydrophobic Fumed Silica Uses

Hydrophobic silica fends off water. It is made by treating regular fumed silica with special chemicals. This variation remains completely dry even in wet conditions. That’s why it prevails in sealers, caulks, and moisture-sensitive electronics. It enlarges silicone rubbers without losing adaptability. In industrial powders, it stops clumping when moisture is high. Outdoor paints and aquatic coatings also utilize it to resist water damages and last much longer.

Both types add stamina, control flow, and improve life span. They are economical fillers that do not alter the color or odor of the end product. Because the powder is really fine, it spreads out equally and operates at low dosages. This saves money and keeps performance high.

Suppliers select this silica for its reliability and large range of uses. Whether you need something that mixes with water or something that obstructs it, this material provides regular outcomes throughout several areas– from building and automobile to personal care and food processing.

5 FAQs of Cheap Hydrophilic and hydrophobic fumed silica dioxide 90%-99% SiO2 content fine white fumed precipitated silica powder

Frequently Asked Questions About Hydrophilic and Hydrophobic Fumed Silica

What is fumed silica?

Fumed silica is a very fine white powder made from silicon dioxide (SiO₂). It has a high purity level—usually between 90% and 99% SiO₂. This material is created through a high-temperature process that gives it unique properties like low density and high surface area.

What’s the difference between hydrophilic and hydrophobic fumed silica?

Hydrophilic fumed silica attracts water. It mixes well in water-based systems. Hydrophobic fumed silica repels water. It is treated with special chemicals so it works better in oils, solvents, or moisture-sensitive products. Choose based on your application needs.

Why use cheap fumed silica?

Affordable fumed silica still offers strong performance for many uses. It acts as a thickener, anti-settling agent, or flow aid. Lower cost does not always mean lower quality—many budget options meet industry standards for purity and particle size.

Where is this silica used?

This powder is common in paints, coatings, adhesives, sealants, cosmetics, and industrial rubbers. Hydrophilic types work in water-based paints. Hydrophobic types are better for waterproof coatings or silicone rubber. It helps control texture, stability, and flow.

Is handling fumed silica safe?

Yes, when handled properly. Always wear gloves, eye protection, and a dust mask. The powder is very light and can become airborne easily. Keep it in a dry place away from moisture. Follow safety instructions on the product label. Store in sealed containers to avoid clumping.
