Abstract
A rubber composition is based on at least: 100 phr of an elastomer matrix comprising an isoprene elastomer and a butadiene elastomer, 20 to 120 phr of a reinforcing filler comprising carbon black as predominant filler, 5 to 120 phr of a plasticizing system comprising, as biobased plasticizer, an ester of a fatty acid and an alcohol selected from fatty alcohols and diol dimers, with a weight-average molar mass (Mw) of less than 5000 g/mol determined by size exclusion chromatography (SEC), and a crosslinking system.
