Beschreibung
Zusammenfassung:	A rubber composition, which allows unexpectedly improved efflorescence performance without deteriorated ozone resistance performance, is based on at least an elastomer matrix; an anti-ozone wax; and a crumb rubber; wherein the elastomer matrix comprises an isoprene elastomer; wherein the total amount of the isoprene elastomer is more than 27.00% by weight per 100.00% by weight of the rubber composition; wherein the total amount of the anti-ozone wax is more than 0.60% by weight and less than 1.70% by weight per 100.00% by weight of the rubber composition; wherein the crumb rubber comprises crumb rubber particles having a particle size of less than 74μm; and wherein a ratio by weight of the total amount of the crumb rubber particles having the particle size of less than 74μm to the total amount of the anti-ozone wax is more than 0.65.
