Abstract

Silicone rubber containing a fumed silica doped with potassium by means of aerosol.

Claims

exact text as granted — not AI-modified

1 . A silicone rubber composition comprising silicone rubber and a fumed silica filler doped with potassium by means of aerosol.  
   
   
       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.
