    摘要: The present invention provides for a coupling system (white filler/diene elastomer) for a rubber composition based on diene elastomer reinforced with a white filler, formed by the association of a polysulphurized alkoxysilane, a zinc dithiophosphate and a guanidine derivative. The invention also provides a rubber composition usable for the manufacture of tires, comprising, as base constituents, one or more diene elastomer(s), a reinforcing white filler, a polysulphurized alkoxysilane coupling agent with which are associated a zinc dithiophosphate and a guanidine derivative. Also provided is a process for preparing such a rubber composition, and a tire or semi-finished product, in particular a tread for a tire, comprising a rubber composition according to the invention.

    摘要: The present invention relates to a tire, the tread of which comprises an elastomer composition comprising: from 10 to 60 phr of a polybutadiene (BR) elastomer; from 10 to 60 phr of a saturated thermoplastic styrene (TPS) elastomer; a reinforcing filler.The combined use of BR and saturated TPS elastomers makes it possible to increase the stiffness and thus to improve the handling performance of the tires, without adversely affecting the hysteresis and therefore the rolling resistance of these tires.

    摘要: A snow tyre with an improved grip on wet ground includes a tread formed of a rubber composition. The rubber composition includes: 20 to 100 phr of a first diene elastomer bearing at least one SiOR function, with R being hydrogen or a hydrocarbon radical, and with phr referring to parts by weight per hunder parts of elastomer; 100 to 160 phr of a reinforcing inorganic filler; and a plasticizing system. The plasticizing system includes: a content A of between 10 and 60 phr of a hydrocarbon resin having a Tg above 20° C.; and a content B of between 10 and 60 phr of a liquid plasticizing agent. A total content A+B is greater than 50 phr. Optionally, the rubber composition also includes 0 to 80 phr of a second diene elastomer.
