Estimating the term…
The present invention is directed to a rubber composition that is useful for the manufacture of tires, where the composition is based on a diene elastomer, a reinforcing inorganic filler, and a coupling system. The coupling system comprises a polysulfurized alkoxysilane (“PSAS”) coupling agent (inorganic filler/diene elastomer) associated with a 1,2-dihydropyridine and a guanidine derivative. The present invention is further directed to tires and semi-finished products for tires comprising a rubber composition according to the invention. The invention is also directed to a coupling system (inorganic filler/diene elastomer) for a rubber composition based on a diene elastomer reinforced by an inorganic filler, where the coupling system comprises a polysulfurized alkoxysilane (PSAS) coupling agent in association with a 1,2-dihydropyridine and a guanidine derivative.
A rubber composition useful for the manufacture of tires, based on a diene elastomer, a reinforcing inorganic filler, and a coupling system, said coupling system comprising a polysulfurized alkoxysilane coupling agent (inorganic filler/diene elastomer) associated with a 1,2-dihydropyridine and a guanidine derivative.
A process for preparing a sulfur-vulcanizable rubber composition useful for the manufacture of tires comprising incorporating by kneading into a diene elastomer, a reinforcing inorganic filler, and a coupling system, said coupling system comprising a polysulfurized alkoxysilane coupling agent (inorganic filler/diene elastomer) associated with a 1,2-dihydropyridine, and a guanidine derivative.
A tire comprising a rubber composition, wherein the rubber composition is based on a diene elastomer, a reinforcing inorganic filler, and a coupling system, said coupling system comprising a polysulfurized alkoxysilane coupling agent (inorganic filler/diene elastomer) associated with a 1,2-dihydropyridine and a guanidine derivative.
A tire tread comprising a rubber composition, wherein the rubber composition is based on a diene elastomer, a reinforcing inorganic filler, and a coupling system, said coupling system comprising a polysulfurized alkoxysilane coupling agent (inorganic filler/diene elastomer) associated with a 1,2-dihydropyridine and a guanidine derivative.
A coupling system (inorganic filler/diene elastomer) for a rubber composition based on a diene elastomer reinforced by an inorganic filler, useful for the manufacture of tires, the coupling system comprising a polysulfurized alkoxysilane coupling agent in association with a 1,2-dihydropyridine and a guanidine derivative.
A semi-finished product for a tire comprising a rubber composition, wherein said rubber composition is based on a diene elastomer, a reinforcing inorganic filler, and a coupling system, said coupling system comprising a polysulfurized alkoxysilane coupling agent (inorganic filler/diene elastomer) associated with a 1,2-dihydropyridine and a guanidine derivative.
