Fumed Silica

Fumed silica is a high-purity, amorphous silicon dioxide produced by the flame hydrolysis of silicon tetrachloride. It is widely used as a thickening, reinforcing, anti-caking, and rheology-modifying agent in a variety of industrial, chemical, and consumer applications.

Key Properties:

• Extremely high surface area for excellent thickening and reinforcing efficiency

• Low bulk density and high dispersibility

• Chemically inert and thermally stable

• Available in hydrophilic and hydrophobic grades to suit various formulations

• Improves flow, suspension, and stability in liquids, gels, and pastes

• Enhances mechanical strength and scratch resistance in coatings and composites

Common Applications:

• Silicone elastomers, sealants, and adhesives

• Paints, coatings, and inks for rheology control

• Plastics and rubber for reinforcement and anti-settling

• Pharmaceutical and food-grade powders as anti-caking agents

• Polishing agents and abrasives

• Cosmetic and personal care formulations
