摘要： A hydrophobic precipitated silica having a BET of less than 110 m2/g, a CTAB of less than 150 m2/g, a BET/CTAB ratio of less than 3, a carbon content of greater than 3.1%, a pH of 9.7 to 10.5, a DBP of less than 230 g/(100 g), and a methanol wettability of more than 50%. The hydrophobic precipitated silica is used in compositions including defoamers, silicone rubber and HTV crosslinkable silicone rubber compositions. The hydrophobic precipitated silica is also useful as a flow assistant and carrier or anti-blocking agent.
