Highly dispersible hydrophilic fumed silica with optimized surface area for rapid wetting and uniform incorporation.
Low bulk density and excellent flowability, enabling efficient handling and dosing in automated production systems.
Consistent particle morphology and narrow aggregate size distribution for predictable rheology control.
Low sodium content, supporting high-purity requirements in electronics-grade and pharmaceutical applications.
Thermally stable up to 1000 °C in inert atmosphere, maintaining structural integrity during high-temperature processing.
Thixotropic agents in high-performance silicone sealants and RTV elastomers.
Rheology modifiers in solvent-based and UV-curable coatings for automotive and industrial finishes.
Free-flow aids and anti-caking agents in specialty powders including pigments, catalysts, and battery materials.
Reinforcing fillers in liquid-phase silicone rubber (LSR) formulations requiring low viscosity and high transparency.
