Functionalized Li-BR in modern tire recipes: a game-changer for low rolling resistance tires

The demand for functionalized Li-BR has surged over the last decade due to its effectiveness in achieving low rolling resistance (RR) in tires. This study highlights the performance enhancements that functionalized Li-BR can provide when paired with functionalized SSBR. Remarkably, even when combined with non-functionalized SSBR, Li-BR demonstrates significant improvements in tire performance compared to conventional high-cis-BR. Additionally, Li-BR promotes easier silica intake, higher silica incorporation and improved mixing efficiency, making it ideal for high-silica recipes. Effective silica dispersion, essential for winter tire traction and stiffness, is greatly supported by Li-BR, underscoring its importance in modern tire formulations.
