Abstract
Elastomer compositions and, in particular, their use as compositions for forming vibration-damping devices. The elastomer compositions comprise brominated isobutylene-co-alkylstyrene, such as brominated isobutylene-co-para-methylstyrene. One or more additives including a reinforcing filler, a processing aid, a scorch retarder, a curing agent, an activator, an accelerator, and any combination thereof may be included in the elastomer composition. The elastomer compositions exhibit physical properties, heat resistance properties, and long life cycle properties making their use in vibration-damping devices particularly suitable.
