Abstract
Plasticizing system usable for the plasticizing of a diene rubber composition. The plasticizing system is based on an MES or TDAE oil and a polylimonene resin. The rubber composition has an improved resistance to abrasion and to cuts, said composition being based on at least a diene elastomer, a reinforcing filler, a cross-linking system and a plasticizing system comprising between 5 and 35 phr of an MES or TDAE oil, and between 5 and 35 phr of a polylimonene resin (phr=parts by weight per hundred of elastomer). Advantageously, this plasticizing system furthermore comprises an unsaturated (C-C) fatty acid triester of glycerol, preferably a glycerol trioleate. A process is disclosed for preparing such a composition. The composition can be used for the manufacture of a finished article or a semi-finished product intended for a suspension system of a motor vehicle, in particular a tire or a tread of such a tire.
