PURPOSE: A rubber composition is provided to be used at high-temperature area in engine, in case of using as a dynamic damper of vehicles, and to maintain initial ride comfort regardless of season or temperature. CONSTITUTION: A rubber composition comprises 100-150 parts by weight of ethylene-propylene rubber, 10-30 parts by weight of paraffin oil, 20-50 parts by weight of inorganic filler, 1-10 parts by weight of peroxide cross linker, 1-10 parts by weight of crosslinking promoter, and 1-10 parts by weight of antiaging agent. The weight average molecular weight of the ethylene-propylene rubber is 260,000-270,000, Mooney viscosity is 20-30, and ethylene content is 40-60 weight%. The inorganic filler is one or more kinds selected from calcium carbonate, talcum, clay, silica, mica, titanium dioxide, carbon black, graphite, woolastonite, and nanosilver.
