| description | A rubber composition, which allows unexpectedly improved tearability performance while being maintained or improved hysteresis performance, is based on at least an elastomer matrix; a reinforcing filler; a plasticizing agent; and a crumb rubber; wherein a ratio by weight of the total amount of the reinforcing filler to that of the plasticizing agent is less than 4.50; wherein the total amount of the reinforcing filler and the crumb rubber is more than 30 phr and less than 70 phr; and wherein a ratio by weight of the total amount of the crumb rubber to that of the reinforcing filler is more than 0.20 and less than 2.50.
L'invention concerne une composition de caoutchouc, permettant d'améliorer de façon inattendue les performances de ruptibilité, tout en préservant ou améliorant les performances d'hystérésis, et comprenant au moins une matrice élastomère ; une charge renforçante ; un agent plastifiant ; et un granulé de caoutchouc ; le rapport en poids entre la quantité totale de la charge renforçante et celle de l'agent plastifiant étant inférieur à 4,50 ; la quantité totale de la charge renforçante et du granulé de caoutchouc étant supérieure à 30 pcc et inférieure à 70 pcc ; et le rapport en poids entre la quantité totale du granulé de caoutchouc et celle de la charge renforçante étant supérieur à 0,20 et inférieur à 2,50. |
