BET 380 m²/g — ultra-high SSA hydrophilic fumed silica
SN-FCT-380 is a hydrophilic fumed silica with ultra-high BET of 380 ± 30 m²/g. SiO₂ ≥ 99.8%, low ignition loss and tightly controlled 45 μm sieve residue make it suitable for silicone rubber, thermosetting paints, reactive adhesives and pharmaceutical carriers — delivering strong thixotropy, thickening and reinforcement at low loadings.
Key Features
- 🔬 Ultra-High SSA Amorphous SiO₂ — Ultra-fine non-crystalline silicon dioxide with BET 100–400 m²/g — molecular activity at the nanoparticle scale
- 🧪 High Purity (≥99.8%) — Produced by flame hydrolysis of silicon tetrachloride (SiCl₄) with trace metal impurities at ppm levels
- ⚙️ Powerful Thixotropy — Forms 3D network structures that dramatically improve viscosity and thixotropy of liquids
- 💧 Hydrophilic & Hydrophobic Grades — Hydrophilic and hydrophobic grades available depending on surface treatment
- 🔥 Heat & Chemical Resistance — Stable under high temperatures, acids, alkalis, and organic solvents — suitable for harsh processes
- ✨ Excellent Reinforcement & Thickening — Simultaneously improves mechanical strength and processability of silicone rubber, adhesives, and sealants
