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 Reolosil Hydrophilic Hydrophobic Aerosil Cabosil Fumed Silica 4.0 Fusil 200 Sf99% White Konasil K200 Particle Powder

Product Overview

Reolosil Hydrophilic Hydrophobic Aerosil Cabosil Fumed Silica 4.0 Fusil 200 SF99% White Konasil K200 is a high-purity fumed silica powder. It appears as a fine, white, free-flowing powder with consistent particle size. This material is widely used as a thickening agent, anti-caking additive, and reinforcing filler across many industries.

Key Properties

The product contains 99% pure silica (SiO₂). Its surface can be either hydrophilic or hydrophobic, depending on treatment. The hydrophilic version absorbs moisture from the air. The hydrophobic type repels water and offers better flow in wet environments. Primary particle size ranges from 5 to 40 nanometers, forming loose agglomerates that break apart easily during mixing.

This fumed silica has a high specific surface area, typically between 150 and 400 m²/g. That gives it strong thickening power even at low dosages. It also shows excellent thermal stability and remains inert under normal conditions.

Common Applications

In paints and coatings, it prevents pigment settling and improves scratch resistance. In adhesives and sealants, it controls sag and boosts strength. Rubber and plastic manufacturers use it to enhance tensile properties and durability. In food, pharmaceuticals, and cosmetics, it acts as a flow aid and anti-caking agent—always meeting strict purity standards.

The hydrophobic grades work well in systems exposed to moisture, like marine coatings or outdoor sealants. The hydrophilic versions suit dry formulations such as powders, toners, and dry mixes.

Handling and Storage

Store the powder in a cool, dry place. Keep containers sealed to avoid moisture uptake (for hydrophilic types) or contamination. Use standard industrial hygiene practices when handling fine powders—wear gloves, eye protection, and a dust mask if needed. Avoid creating airborne dust.

Applications of Hydrophilic and Hydrophobic Fumed Silica Powders

Key Uses Across Industries

Fumed silica powders like Reolosil, Aerosil, Cab-O-Sil, Fusil 200, Konasil K200, and similar grades are extensively utilized in numerous industries. These materials come in both hydrophilic (water-attracting) and hydrophobic (water-repelling) types. Each kind offers various objectives based upon its surface residential properties.

In paints and coverings, fumed silica works as a thickening representative. It aids prevent pigments from settling. It additionally gives better control during application. This results in smoother coatings and enhanced sturdiness.

Adhesives and sealants rely on fumed silica for reinforcement. The powder enhances strength without making the product as well rigid. It also quits liquid components from leaking out with time. This maintains efficiency secure throughout storage space and use.

In cosmetics, hydrophobic fumed silica boosts texture. It soaks up excess oil on the skin. It additionally assists powders circulation equally. Many foundations, eye shadows, and sun blocks include it for these reasons.

Rubber and plastic suppliers include fumed silica to boost mechanical buildings. It boosts tear resistance and tensile toughness. In silicone rubber, it is essential for accomplishing high clearness and flexibility.

Pharmaceutical products utilize fumed silica as a flow help. It makes sure powders move efficiently throughout tablet manufacturing. This lowers blocking and boosts uniformity in application.

Food-grade variations are approved as anti-caking agents. They maintain powdered active ingredients free-flowing in completely dry mixes like seasonings, consume powders, and baking aids.

Electronic devices advantage too. Fumed silica fills gaps in thermal interface materials. It helps manage warm without performing electrical power.

Each grade– whether identified SF99%, white, or particle powder— is selected based upon pureness, area, and therapy. Individuals match the silica type to their details process needs for finest results.

5 FAQs of Reolosil Hydrophilic Hydrophobic Aerosil Cabosil Fumed Silica 4.0 Fusil 200 Sf99% White Konasil K200 Particle Powder

Frequently Asked Questions

What is this fumed silica powder used for?

This white powder works as a thickener, anti-settling agent, and flow aid. People add it to paints, coatings, adhesives, sealants, and cosmetics. It helps control how liquids move and keeps solid particles from sinking.

Is it hydrophilic or hydrophobic?

The base material is hydrophilic. That means it mixes well with water and polar liquids. If you need a water-repelling version, surface-treated grades are available. Always check the product code or ask your supplier before buying.

How do I mix it into my product?

Add the powder slowly while stirring. Use high-shear mixing if possible. This breaks up clumps and spreads the silica evenly. Do not dump it all at once. That can cause lumps that are hard to remove later.

Is this powder safe to handle?

Wear gloves, safety glasses, and a dust mask when working with the powder. It is not highly toxic, but fine dust can irritate your eyes, skin, and lungs. Keep the container closed when not in use. Store it in a dry place away from moisture.

Why are there so many names like Aerosil, Cab-O-Sil, and Konasil?

These are brand names from different makers. They all refer to fumed silica made the same way—burning silicon tetrachloride in a flame. The core material is nearly identical. Small differences may exist in particle size or surface area. Always test a sample in your system before full-scale use.
