ZEMSIL FS-300

English

ZEMSIL FS-300 is a high-surface-area hydrophilic fumed silica at 300 m²/g, equivalent to Aerosil 300. Smaller primary particles (~7 nm) and higher silanol density provide superior reinforcement in silicone rubber and stronger thickening versus the 200 m²/g grade. Preferred for demanding HTV and LSR formulations requiring high tear strength and tensile properties.
