2. The silicone rubber composition according to claim 1, wherein the fumed silica filler is an oxide which has been prepared pyrogenically by flame oxidation or by flame hydrolysis and which is doped with from 0.000001 to 40 wt. % of a doping substance, the BET surface area of the doped oxide being from 10 to 1000 m 2/g and the DBP absorption of the fumed oxide being undetectable or being less than 85% of the normal value for that fumed silica.
3. The silicone rubber composition according to claim 1 wherein the silicone rubber is a LSR silicone rubber.
4. The silicone rubber composition according to claim 1 wherein the silicone rubber is a HTV silicone rubber.
