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 (C12-C22) 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.

Abstract: The inventive plasticising system is used for plasticising a dienic rubber compound is characterised in that it is based on a MES or TDAE oil and a polylimonene resin. Said rubber compound exhibits an improved abrasion and cut resistance and is based on at least one type of dienic elastomer, a reinforcing filler, a cross-linking system and a plasticising system comprising from 5 to 35 to 35 pce of the MES or TDAE oil and from 5 to 35 to 35 pce of polylimonene resin (pce=parts by weight percent elastomer). Advantageously, said plasticising system also comprises a glycerol unsaturated fatty acid triester (C12-C22), preferably a glycerol trifoliate. The inventive method for producing said compound, using the compound for producing a final or semi-final product for the gripping system of a motor vehicle with ground, in particular the tire or the thread thereof are also disclosed.
