Abstract
Silicone rubber compositions are disclosed including a silicone polymer and a silicon-treated carbon black. The silicon-treated carbon blacks include a silicon-containing compound that is distributed through at least a portion of the carbon black aggregate. The silicon-treated carbon black is incorporated within a silicone rubber composition as an alternative reinforcing and extending filler, imparting higher hardness to elastomers formed from the composition, when compared to silicone rubber compositions incorporating an untreated carbon black.
