Beschreibung
Zusammenfassung:	A rubber composition for vibration damping rubbers, comprising, a rubber component which comprises at least one selected from the group consisting of natural rubbers and polyisoprene rubbers in an amount of 60 to 95 parts by weight, and which comprises a styrene butadiene rubber in an amount of 5 to 30 parts by weight and a complex zinc flower in an amount of 2 to 10 parts by weight for 100 parts by weight of the rubber component. The complex zinc flower has a nitrogen adsorption specific surface area of 15 to 110 m 2 /g, a DBP oil absorption amount of 50 to 100 mL/100 g, and a zinc flower concentration of 38 to 64% by weight.
