Highly pure, pyrogenically produced amorphous silica with exceptional surface area and nanostructured morphology.
Outstanding reinforcing and thickening performance in non-aqueous systems due to strong hydrogen-bonding capability.
Excellent dispersion stability in solvents, resins, and polymer matrices without requiring surface treatment.
Low bulk density and high flowability enabling consistent handling and metering in industrial processes.
Thermally stable up to 1000 °C, supporting high-temperature processing and end-use applications.
Thixotropic agent in high-performance coatings and industrial paints.
Reinforcing filler in silicone elastomers and RTV/HTV rubber compounds.
Viscosity modifier and anti-settling agent in adhesives and sealants.
Free-flow aid and carrier for active ingredients in agrochemical formulations.
Stabilizer and rheology modifier in specialty inks and electronic pastes.
