High specific surface area (~200 m²/g) for exceptional reinforcement and thickening efficiency.
Hydrophilic surface chemistry enabling easy dispersion in polar systems including water, alcohols, and glycols.
Low bulk density and excellent flowability for consistent handling and metering in industrial processes.
Consistent particle morphology and narrow agglomerate size distribution ensuring reproducible rheology control.
Free of added surface treatments or coupling agents — ideal for applications requiring high purity and thermal stability.
Rheology modifier and anti-settling agent in water-based paints and architectural coatings.
Thickener and suspension stabilizer in liquid detergents and personal care formulations (e.g., shampoos, gels).
Reinforcing filler in silicone elastomers and RTV/HTV silicone rubber compounds.
Free-flow aid and anticaking agent in high-performance pharmaceutical and food-grade powders.
Viscosity builder and sag resistance enhancer in adhesives and sealants based on acrylics and polyurethanes.
