La présente invention concerne une composition de caoutchouc à base d'au moins une matrice élastomère, une charge renforçante, un système de vulcanisation et un système plastifiant comprenant au moins un ester spécifique d'acide gras de masse molaire moyenne en poids (Mw) inférieure à 5000 g/mol, choisi parmi les monoesters d'acide gras et d'alcool gras et les diesters d'acide gras avec un dimère diol, comme plastifiant biosourcé. The present invention relates to a rubber composition based on at least one elastomer matrix, a reinforcing filler, a vulcanization system and a plasticizing system comprising at least one specific fatty acid ester that has a weight-average molar mass (Mw) of less than 5000 g/mol and is chosen from fatty acid and fatty alcohol monoesters and fatty acid diesters with a diol dimer, as a bio-based plasticizer.
