Product Name:Fumed silica
English Name:Fumed silica
CAS No.:99439-28-8
Aliases:Nano silica dispersion (physical method)
Molecular Formula:SiO2
Physical Properties:Milky white liquid, stable, and easily soluble in more material systems. It has a large specific surface area with abundant unsaturated residual bonds and hydroxyl groups in different bonding states, exhibiting high reactivity. It shows high reflectivity to both UV and visible light. Purity reaches above 99.99%. Density: 1.35-1.40 g/cm³ (25°C), pH: 6.00-7.00, viscosity: 70.00-80.00 mPa·s (25°C), solvent: water.
Uses:Widely used in coatings and paints as thickening, thixotropic, anti-settling, and anti-sagging agent, increasing coating hardness and weather resistance. It improves brightness and contrast in water-based inks. In adhesives, it provides reinforcement, thickening, and rheology control. It serves as a reinforcing filler in rubber and latex to improve mechanical properties. In plastics, fibers, and films, it enhances strength, toughness, and abrasion resistance. It is used in paper coatings for better ink absorption, and in CMP slurry it is non-corrosive, non-damaging, and safe to use.
