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 Factory Supply High Purity Silica fumed / Silicon dioxide / acticel CAS 112945-52-5

This high purity silica fume, also called fumed silica or silicon dioxide (CAS 112945-52-5), is incredibly useful. Its tiny particle size and huge surface area create unique properties. Builders rely on it heavily. Adding it to concrete and cement makes them much stronger and more durable. It fills spaces between cement grains. This makes the concrete denser. Water and chemicals struggle to penetrate it. Structures last longer. Roads and bridges benefit greatly.

The coatings industry uses it extensively. It acts as a thickener and prevents settling in paints and coatings. You get smooth application and a nice finish. It also fights sagging on vertical surfaces. The particles form a network. This controls the flow behavior, called rheology. Industrial coatings need this control.

Adhesives and sealants get a big boost from this silica. It thickens them effectively. It stops fillers from sinking to the bottom. Application becomes easier and more consistent. The bond strength often improves too. Silicone rubber absolutely requires it. This silica is the main reinforcing filler. It gives silicone rubber its strength and elasticity. Without it, silicone products would be weak. Things like gaskets and seals depend on it.

Pharmaceuticals use it sometimes. It can act as a flow aid for powders. It helps powders move freely during processing. Some drug formulations use it for this reason. High-end electronics find uses for it. Its purity and fine particle size are key. It might be used in special composites or polishing slurries. This silica is a versatile workhorse material. Its unique physical properties solve problems across many industries. It improves product performance significantly.
