Fumed Silica is a high-purity amorphous silica produced by the hydrolysis of chlorosilanes in a flame. It offers high surface area, strong thickening ability, and excellent rheology control. With its naturally hydrophilic surface, it disperses well in aqueous systems.
Key Features:
High purity and consistency
Excellent thixotropic and anti-settling performance
Reinforcing and thickening effect
Available in various BET surface areas (150–400 m²/g)
Toothpaste and oral care
Silicone sealants and adhesives
Paints, inks, coatings
Unsaturated polyester resins
Cosmetics and pharmaceuticals
Food anti-caking (under specified grades)
FS-150：BET 150 ± 15 m²/g（Commonly used in coatings, adhesives）
FS-200：BET 200 ± 20 m²/g（Commonly used in toothpaste, cosmetics）
