Tread tire, useful in motor vehicles including e.g. sport utility vehicles, comprises e.g. rubber composition comprising first elastomer comprising diene elastomer and second elastomer comprising thermoplastic polyurethane block copolymer

摘要

Tread tire comprises a rubber composition comprising at least a first elastomer comprising a diene elastomer, a second elastomer comprising thermoplastic polyurethane block copolymer with polyurethane and polydiene blocks, 70-50 parts per hundred of rubber (phr) of a reinforcing inorganic filler, a plasticizing system comprising 5-60 phr of a hydrocarbon resin (A) having a glass transition temperature (Tg) of greater than 20[deg] C and 5-60 phr of a liquid plasticizer (B) (plasticized at 20[deg] C) having a Tg of less than -20[deg] C, where the contents of A and B are greater than 30 phr.
