Abstract: The present invention relates to elastomeric compounds including an elastomer and a silicon-treated carbon black, and optionally including a coupling agent. The elastomeric compound exhibits poorer abrasion resistance in the absence of a coupling agent, lower hysteresis at high temperature and comparable or increased hysteresis at low temperature compared to an elastomer containing an untreated carbon black. A variety of elastomers and formulations employing such elastomers are contemplated and disclosed. Elastomeric compounds incorporating an elastomer and an oxidized, silicon-treated carbon black are also disclosed. Also disclosed are methods for preparing elastomers compounded with the treated carbon black.
