Abstract
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, lower hysterisis at high temperature and comparable or increased hysterisis at low temperature compared to an elastomer containing an untreated carbon black. Elastomeric compounds incorporating an elastomer and an oxidized, silicon-treated carbon black are also disclosed. Also disclosed is method for preparing elastomers compounded with the treated carbon black.
