Title (EN) RUBBER COMPOSITION CONTAINING A BLEND OF SILICAS AND RELATED PROCESSES FOR IMPROVING WEAR
(FR) COMPOSITION DE CAOUTCHOUC CONTENANT UN MÉLANGE DE SILICES ET PROCÉDÉS ASSOCIÉS POUR AMÉLIORER L'USURE
Abstract:
(EN) Disclosed herein are rubber compositions comprising: (a) natural rubber, polyisoprene, or a combination thereof; (b) at least one conjugated diene monomer containing polymer or polymer; (c) a first silica filler having a BET surface area of at least 220 m2/g; (d) a second silica filler having a BET surface area lower than that of the first silica filler and greater than 135 m2/g; and (e) optionally carbon black filler.
(FR) L'invention concerne des compositions de caoutchouc comprenant : (a) du caoutchouc naturel, du polyisoprène ou une combinaison de ces derniers ; (b) au moins un polymère contenant un monomère diène conjugué ou un polymère ; (c) une première charge de silice ayant une surface BET d'au moins 220 m2/g ; (d) une seconde charge de silice ayant une surface BET inférieure à celle de la première charge de silice et supérieure à 135 m2/g ; et (e) éventuellement une charge de noir de carbone.
