Highly pure, hydrophilic fumed silica with consistent particle morphology and narrow primary particle size distribution.
Optimized surface area (~30 m²/g) for balanced reinforcement, thickening, and anti-settling performance.
Excellent dispersion stability in both polar and non-polar liquid systems without requiring extensive surface treatment.
Low abrasivity and high flowability, enabling smooth handling and efficient incorporation into formulations.
Complies with major food-contact and pharmaceutical regulatory guidelines (e.g., FDA 21 CFR §172.375, EFSA).
Thickener and rheology modifier in silicone elastomers and RTV/HTV compounds.
Anti-caking agent and free-flow aid in powdered food supplements and pharmaceutical excipients.
Reinforcing filler in high-transparency liquid silicone rubber (LSR) for medical devices.
Viscosity stabilizer in solvent-based coatings, inks, and adhesives.
Performance additive in lithium-ion battery electrolyte gels and separator coatings.
