<p>Provided is a hydrophilic precipitated silica which is well suited to use in silicone rubber formulations (RTV-1, RTV-2, HTV and LSR), particularly well suited to use in HTV silicone rubber formulations. It has a BET surface area of 185~260 m<sup>2</sup>/g, a CTAB surface area of 100~160 m<sup>2</sup>/g, a BET/CTAB ratio of 1.2~2.6, and a conductivity of <250μS/cm. Also provided are a process for producing the precipitated silica and the use of the precipitated silica for thickening and reinforcing silicone rubber formulations.</p> |
