High specific surface area (~200 m²/g) for superior reinforcement and thickening performance.
Excellent dispersion stability in both polar and non-polar systems due to optimized surface silanol density.
Low bulk density and free-flowing powder morphology, enabling easy handling and uniform incorporation.
Consistent batch-to-batch quality with strict control over aggregate size and purity.
Hydrophobic surface treatment available upon request for enhanced compatibility in organic media.
Thixotropic agent in high-performance silicone sealants and adhesives.
Rheology modifier in industrial coatings and automotive refinish paints.
Reinforcing filler in liquid silicone rubber (LSR) formulations.
Anti-caking and flow aid in pharmaceutical and food-grade powders.
Viscosity stabilizer in lithium battery electrolyte gels and energy storage systems.
