PURPOSE: A rubber composition for an engine mount is provided, to improve heat resistance and durability and to reduce the deterioration of physical properties after aging for preventing the deterioration of an engine room due to a high temperature. CONSTITUTION: The rubber composition comprises 100 parts by weight of ethylene propylene diene rubber containing 6-9 wt% of ethylidene norbornene and 50-70 wt% of ethylene; 0.5-2.0 wt% of a vulcanizing agent; 0.3-2.5 wt% of an accelerator; and 30-60 parts by weight of a filler. Preferably the vulcanizing agent is sulfur; the accelerator is N-cyclohexyl-2-benzothiazylsulfenamide, tetramethyl thiuram disulfide or their mixture; and the filler is carbon black with a particle size of 27-70 micrometers. |
