Disclosed is a vibration-proof rubber composition having improved physical properties such as dynamic ratio, loss factor, etc. without sacrificing, for example, long-term durability. More particularly, the vibration-proof rubber composition, which contains a natural rubber as well as a styrene-butadiene rubber or a butadiene rubber as base rubber together with a filler and suitable additives, provides improved comfort, driving stability and impact shock of an automobile by improving dynamic ratio and loss factor while maintaining long-term durability. |
