## Abstract

Disclosed is a vibration reducing rubber composition, more specifically to a vibration reducing rubber composition that reduces inflow of vibration and noise generated from an engine into an interior of an automobile, and improves riding comfort, emotional quality and merchantable quality of the automobile, by providing a particular formulation of a heater hose composition, which comprises ethylene propylene rubber (EPDM), fast extruding furnace (FEF) carbon black and semi reinforcing furnace (SRF) carbon black.

## Claims

### Claim 1

A vibration reducing rubber composition comprising ethylene propylene rubber (EPDM), fast extruding furnace (FEF) carbon black and semi reinforcing furnace (SRF) carbon black.

### Claim 2 (depends on 1)

The vibration reducing rubber composition according to claim 1, which further comprises a filler and a plasticizer.

### Claim 3 (depends on 1)

The vibration reducing rubber composition according to claim 1, wherein Mooney viscosity (ML1+8, 125° C.) of the ethylene propylene rubber (EPDM) is about 48 to 68.

### Claim 4 (depends on 1)

The vibration reducing rubber composition according to claim 1, which comprises about 100 to 140 parts by weigh of the semi reinforcing furnace (SRF) carbon black based on 100 parts by weight of the fast extruding furnace (FEF) carbon black.

### Claim 5 (depends on 2)

The vibration reducing rubber composition according to claim 2, which comprises about 60 parts by weight of the fast extruding furnace (FEF) carbon black, about 85 parts by weight of the semi reinforcing furnace (SRF) carbon black, about 30 parts by weight of the filler, and about 75 parts by weight of the plasticizer based on 100 parts by weight of the ethylene propylene rubber (EPDM).

### Claim 6 (depends on 1)

A heater hose for an automobile comprising the vibration reducing rubber composition according to claim 1.
