Application of bifunctionalized solution-polymerized styrene-butadiene rubber in tire tread compound

Trial production and performance evaluation of finished tires were conducted with domestically produced double-end functional solutionpolymerized styrene-butadiene rubber SSBR 2060-N and single-end functional product ■from Zeon Corporation of Japan. The results showed that the finished tires produced from SSBR 2060-N conformed to the technical standards in terms of external dimensions, and the wet-skid resistance and rolling resistance met the double B-class tire specified by the tire labeling regulations EU 2020/740, jointly enacted by the European Parliament and the Council of the European Union. The strength performance, high-speed performance, and durability of the tires were comparable to those of the finished tire prepared with ■ and met the requirements of national standards.
