Disclosed are 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.
