Fumed Silica

Overview of Fumed Silica Powder

Fumed silica powder, also known as pyrogenic silica, is an ultra-fine amorphous form of silicon dioxide produced through the combustion of silicon tetrachloride in an oxygen-rich hydrogen flame. This versatile material offers exceptional thixotropic properties, making it ideal for enhancing the rheological characteristics of various products.

Features of Fumed Silica Powder

• High Surface Area: Provides excellent thickening and anti-settling properties.
• Thixotropy: Enhances flowability and stability in liquid systems.
• Chemical Purity: Consistent composition with minimal impurities.
• Hydrophilic/Hydrophobic Variants: Suitable for a wide range of applications.

Applications of Fumed Silica Powder

Fumed silica is widely used in industries such as:

• Coatings and Paints: Improves anti-sagging and anti-settling properties.
• Adhesives and Sealants: Enhances mechanical strength and durability.
• Cosmetics: Acts as a thickener and stabilizer.
• Pharmaceuticals: Used as a carrier for active ingredients.
