Abstract:
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 m2/g, a CTAB surface area of 100˜160 m2/g, a BET/CTAB ratio of 1.2˜2.6, and a conductivity of
