RUBBER COMPOSITION AND USE THEREOF

摘要

A rubber composition which is excellent in sealing properties and acid resistance, has a low reaction force and low hardness, is reduced in compression set, and especially has such high heat resistance that the composition does not crack even when used under high-temperature high-compression conditions. Also provided are a use of the rubber composition and a main body including the rubber composition mounted thereon. The rubber composition is characterized by comprising an ethylene/a-olefin/unconjugated polyene copolymer [A] and burned talc [B].
