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 Hot high Quality Hydrophilic Silica Dioxide Nano Grade 200 Pyrogenic Silica Powder Fumed Silica 200

This Hydrophilic Silica Dioxide Nano Grade 200 powder is top quality fumed silica. It’s made using a special high-temperature process. This creates very pure silicon dioxide. Its main chemical is SiO2. The purity is very high, over 99.8%. This powder is hydrophilic. Water molecules stick easily to its surface.

The particles are extremely small. They are in the nanometer size range. The average particle size is about 12 nanometers. These tiny particles form larger groups. These groups have a low bulk density. It’s usually between 30 and 50 grams per liter. The surface area is very large. It’s around 200 square meters per gram. This big surface area is key for its performance.

The powder looks white. It feels fluffy. The pH value is neutral. It’s typically between 3.6 and 4.3. This powder is very light. It flows easily. It helps thicken liquids. It controls how liquids flow. It prevents settling in mixtures. It stops caking in powders.

This fumed silica grade 200 is used in many industries. It works well in paints and coatings. It improves the texture. It helps adhesives and sealants perform better. It makes silicone rubber stronger. It acts as a free-flow agent for powders. It finds uses in cosmetics and pharmaceuticals. It works in food applications too. It’s a versatile additive.

5 FAQs of Hot high Quality Hydrophilic Silica Dioxide Nano Grade 200 Pyrogenic Silica Powder Fumed Silica 200

What is hydrophilic fumed silica?
This is a very fine white powder. People also call it pyrogenic silica. It’s made by burning silicon tetrachloride in a hydrogen-oxygen flame. This creates tiny particles. These particles group together in chains. The powder is called “hydrophilic” because it attracts water easily. The “nano grade 200” part means the particles are extremely small. Their surface area is about 200 square meters per gram.

Why use this specific grade, Fumed Silica 200?
Grade 200 offers a high surface area. This large surface gives it excellent thickening power. It works well to thicken liquids and pastes. It also stops powders from caking. It acts as a free-flow agent. These properties make it valuable in many industries. You find it in paints, coatings, adhesives, sealants, and even food products.

How does it work as a thickener?
The tiny silica particles form a network inside liquids. Think of it like a very fine web. This web structure traps the liquid molecules. Trapping the liquid makes it harder for the mixture to flow. This thickening happens even at low silica levels. It prevents settling and separation. The result is a stable, uniform product.

Is this material safe to handle?
Handle any fine powder carefully. Avoid breathing in the dust. Use standard safety gear like gloves and dust masks. Work in well-ventilated areas. Fumed silica itself is chemically inert. It doesn’t readily react. It’s non-toxic. Many grades meet food contact regulations. Always check the specific product’s safety data sheet first. Follow the supplier’s handling instructions.

Where is Hydrophilic Fumed Silica 200 typically used?
Its uses are wide. It thickens paints and printing inks. It prevents sagging. It acts as an anti-settling agent. In adhesives and sealants, it controls flow and prevents dripping. It improves reinforcement. The food industry uses it as an anti-caking agent in powders like spices. It keeps powders free-flowing. It also finds use in cosmetics, pharmaceuticals, and silicone rubber production.
