Elastomeric compounds incorporating silicon-treated carbon blacks.U.S. patent: 7,199,176 Issued: April 3, 2007 Inventors: Khaled Mahmud Khaled Mahmud (Bengali: খালেদ মাহমুদ) (born July 26, 1971 in Dhaka) is a Bangladeshi cricketer. , Meng-Jiao Wang, Robert A. Francis, James A. Belmont Assigned: Cabot Key statement: Disclosed are elastomeric compounds including an elastomer elastomer (ĭlăs`təmər), substance having to some extent the elastic properties of natural rubber. The term is sometimes used technically to distinguish synthetic rubbers and rubberlike plastics from natural rubber. 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 hysteresis (hĭs'tərē`sĭs), phenomenon in which the response of a physical system to an external influence depends not only on the present magnitude of that influence but also on the previous history of the system. 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 oxidized having been modified by the process of oxidation. oxidized cellulose see absorbable cellulose. , silicon-treated carbon black are also disclosed. Also disclosed are methods for preparing elastomers compounded with the treated carbon black. |
