Title
(EN) HYDROGENATED RUBBER COMPOSITION
(FR) COMPOSITION DE CAOUTCHOUC HYDROGENE
Abstract
(EN)
A hydrogenated rubber composition comprising: (A) 100 parts by weight of a feedstock rubber containing at least 30 wt.% of at least one partially hydrogenated conjugated diene rubber with 5-70 % of the double bonds thereof hydrogenated; (B) 10-150 parts by weight of silica; (C) 0.1-20 parts by weight of an organic silane coupling agent; (D) 0.1-10 parts by weight of a vulcanizing agent; and, if necessary, (E) 5-80 parts by weight of carbon black. The composition is remarkably excellent in rebound resilience and prevention of heat buildup and also excellent in wet-skid resistance and has improved processability, thus being usable for producing various automotive tires, damping rubbers, belts and other industrial parts. Particular examples of the suitable uses thereof in the automotive tires include treads, cap treads and undertreads, and the use of such tires serves to improve the fuel efficiency of automobiles equipped therewith and save the fuel consumption thereof.
(FR)
Une composition de caoutchouc hydrogéné comprend: (A) 100 parties en poids d'une charge de caoutchouc contenant au moins 30 % en poids d'au moins un caoutchouc diène conjugué partiellement hydrogéné avec 5 à 70 % de ses liaisons doubles hydrogénées, (B) 10 à 150 parties en poids de dioxyde de silicium, (C) 0,1 à 20 parties en poids d'un agent de couplage à base de silane organique, (D) 0,1 à 10 parties en poids d'un agent de vulcanisation et, si nécessaire, (E) 5 à 80 parties en poids de noir de carbone. La composition présente d'excellentes caractéristiques de rebondissement élastique et est remarquable dans la prévention de l'accumulation de chaleur; elle présente également d'excellentes caractéristiques d'adhérence sur chaussée mouillée et une meilleure faculté de mise en oeuvre. Elle peut par conséquent être utilisée pour produire divers pneus d'automobile, les caoutchoucs d'amortissement, les courroies et autres pièces industrielles. Dans la production de pneus d'automobile, elle est notamment appropriée pour former les bandes de roulement, les bandes de roulement supérieures et inférieures, et les pneus comportant ce type de bande favorisent l'économie en carburant des automobiles qui en sont équipées.
