| 简介 |
A rubber composition used for forming a tread of a tire includes an elastomer matrix, a reinforcing filler, and a coupling agent. The elastomer matrix includes from 60 to 95 phr of at least one diene elastomer and from 5 to 40 phr of a polar thermoplastic elastomer (TPE). The polar TPE includes at least one elastomer block and one polar thermoplastic block selected from a homopolymer or copolymers of an alkylacrylic acid ester, with an alkyl radical containing 1 to 4 carbon atoms. The reinforcing filler includes a reinforcing inorganic filler. The presence of the polar TPE makes it possible to improve a compromise of wet grip and dry grip performances of the tread. |
