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 99.9 Silica Hydrophilic Synthetic Amorphous Silica Fumed Nano Fumed Silica 200

99.9% Silica Hydrophilic Synthetic Amorphous Fumed Nano Silica 200

Item Overview

This product is a high-purity artificial amorphous silica made with flame hydrolysis. It has 99.9% SiO two and brings a hydrophilic surface area, which indicates it mixes well with water-based systems. The product appears as a fine, free-flowing white powder with really reduced mass thickness.

Key Features

Ultrafine fragment dimension: Key fragments determine around 12 nanometers. These tiny bits develop loose, chain-like aggregates that develop a big surface– around 200 m TWO/ g. This framework provides the silica solid thickening and anti-settling residential properties.

Pure and constant: Made under rigorous controls, the silica has minimal pollutants. Hefty metals and other impurities are kept well listed below market limits. Batch-to-batch performance stays stable, making it trusted for delicate applications.

Hydrophilic nature: The surface consists of silanol (Si-OH) teams. These enable strong hydrogen bonding with water and polar liquids. Therefore, the powder distributes quickly in liquid solutions without needing surface treatment.

Usual Uses

This fumed silica works well in layers, adhesives, sealers, and paints to avoid pigment settling and control flow. It likewise adds body to cosmetics like lotions and lotions. In industrial liquids, it serves as a thixotropic agent– thick when still, slim when stirred. Battery manufacturers use it to support electrolytes. Food and pharmaceutical producers might utilize it as an anti-caking representative, supplied it satisfies relevant safety standards.

Handling and Storage

Store in a completely dry, awesome location away from wetness. Maintain containers securely shut when not in use. Usage conventional dust control actions during handling to avoid inhalation. Wear handwear covers and eye protection as a basic safety action.

Applications of 99.9 Silica Hydrophilic Synthetic Amorphous Silica Fumed Nano Fumed Silica 200

Applications of 99.9% Pure Hydrophilic Fumed Silica (Aerosil ® 200)

Enlarging and Rheology Control

99.9% pure hydrophilic fumed silica is commonly used to change the flow and density of fluids. It aids stop pigments from sinking in paints and keeps fragments equally spread out in coverings. This silica offers items a smooth, steady texture without changing their quality.

Reinforcement in Silicone Rubbers

In high-performance silicone rubbers, this fumed silica works as a solid filler. It boosts tensile stamina, tear resistance, and sturdiness. The result is versatile yet tough rubber parts utilized in medical gadgets, vehicle seals, and kitchenware.

Anti-Caking Representative in Powders

Dry powder items like spices, instant beverages, and drugs usually clump with each other. Including a small amount of hydrophilic fumed silica maintains them free-flowing. It soaks up wetness and produces area between particles, so the powder pours conveniently whenever.

Matting and Surface Area Effects

Paints, varnishes, and printing inks utilize this silica to produce a soft, non-reflective coating. It regulates gloss levels while enhancing scrape resistance. The surface remains clean and preserves its evaluate time.

Stabilizer in Adhesives and Sealants

This silica stops fluid adhesives from leaking or sagging after application. It holds fillers in position and sustains long-term efficiency under warm or stress. Users get regular results with cleaner sides and far better bond toughness.

Usage in Cosmetics and Personal Treatment

Because it is ultra-pure and secure, this fumed silica appears in foundations, powders, and creams. It enhances structure, helps take in oil, and gives a smooth feeling on the skin. Products remain smooth and do not separate in the container.

5 FAQs of 99.9 Silica Hydrophilic Synthetic Amorphous Silica Fumed Nano Fumed Silica 200

Frequently Asked Questions: 99.9% Silica Hydrophilic Synthetic Amorphous Fumed Nano Silica 200

What is hydrophilic fumed silica?

Hydrophilic fumed silica is a very fine powder made from pure silicon dioxide (SiO₂). It has a strong attraction to water. This product contains 99.9% silica and is created through a high-temperature process that forms nano-sized particles with a large surface area.

How does it work in liquids?

When added to liquids, the silica particles form a network that thickens the mixture. It helps prevent solids from settling and keeps ingredients evenly mixed. Because it is hydrophilic, it works well in water-based systems like paints, adhesives, and coatings.

Is this silica safe to use?

Yes. This fumed silica is synthetic and amorphous, not crystalline. That means it does not carry the same health risks as crystalline silica. Always follow safety guidelines when handling fine powders—use gloves, eye protection, and avoid breathing dust.

What makes grade 200 different?

Grade 200 refers to its specific surface area of about 200 m²/g. A higher surface area means better thickening and anti-settling performance. This grade offers strong reinforcement in small amounts, making it efficient for industrial use.

Where is it commonly used?

This silica is used in many industries. You’ll find it in paints, inks, adhesives, sealants, cosmetics, and even some food and pharmaceutical products. It improves texture, stability, and flow control without changing the chemical nature of the base material.
