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 Powdered White Cabosil M5 Silicon Dioxide Fumed Silica

This product is a high-purity fumed silica made from silicon dioxide. It comes as a fine white powder with low moisture content. The material acts as a thickening agent, rheology modifier, and anti-settling additive. It works in liquid systems to control flow behavior.

The primary particle size ranges between 0.2-0.3 micrometers. The surface area is 200±15 square meters per gram. Bulk density sits at 30-50 grams per liter. Tamped density is higher, around 50-70 grams per liter. The pH value in a 4% water dispersion is 3.7-4.3. Moisture content stays below 1.5% when heated to 105°C. Silicon dioxide purity exceeds 99.8%.

This powder is free-flowing and non-caking. It resists clumping under normal storage conditions. The particles form three-dimensional networks when mixed into liquids. This structure increases viscosity without changing the system’s clarity. It prevents settling of solid components in suspensions.

Common applications include coatings, adhesives, and sealants. It thickens epoxy resins, polyester compounds, and silicone rubbers. In paints, it improves sag resistance and leveling. For gels and pastes, it provides stable texture. The product is compatible with polar and non-polar liquids. It works well in solvent-based and water-based systems.

The powder is chemically inert. It does not react with most substances. Thermal stability remains up to 600°C. Electrical insulation properties are strong. It resists UV radiation and oxidation.

In cosmetics, it adjusts the consistency of creams and lotions. Pharmaceutical uses include tablet coatings and viscosity control in gels. Food-grade versions serve as anticaking agents. Industrial uses cover inks, lubricants, and ceramics.

Handling requires standard safety measures. Use dust masks to avoid inhalation. Store in a dry, cool place away from moisture. Keep containers tightly sealed. The material is non-toxic but may cause mild irritation with prolonged exposure.

Packaging options include 5-kilogram bags, 20-kilogram cartons, or bulk containers. Custom sizes are available. Shelf life exceeds two years when stored properly.
