Highly pure, pyrogenically produced amorphous silica with low sodium and heavy metal content.
Optimized surface chemistry for excellent dispersion stability in polar and non-polar systems.
Controlled primary particle size (~15 nm) enabling superior reinforcement and rheology control.
Low bulk density and high specific surface area (~130–150 m²/g) for efficient thickening and anti-settling performance.
Hydrophobic surface treatment ensures moisture resistance and enhanced compatibility with organic matrices.
Thixotropic agent in high-performance silicone sealants and adhesives.
Rheology modifier in UV-curable coatings and inks.
Reinforcing filler in liquid silicone rubber (LSR) formulations.
Anti-caking additive in pharmaceutical and food-grade powders.
Viscosity stabilizer in battery electrolyte gels and lithium-ion battery slurries.
