RUBBER COMPOSITION FOR TIRE, TIRE MEMBER, METHOD FOR PRODUCING BIOMASS-DERIVED RUBBER, AND PNEUMATIC TIRE |
摘要 |
The present invention provides rubber compositions for tires capable of providing tire components and pneumatic tires having low-temperature properties and abrasion resistance that are equivalent to those of tire components and pneumatic tires formed from conventional synthetic rubber, respectively, while meeting the demand for a sound material-cycle society. The present invention relates to rubber compositions for tires containing a biomass-derived rubber obtained by polymerizing a biomass-derived monomer component, the biomass-derived rubber having a pMC (percent modern carbon) value of 1% or greater as determined in conformity with ASTM D6866-10, and having a Tg (glass transition temperature) value of -120°C to-80°C. |
