Presentation

Functionality versus molecular weight of SSBR for better performance

Functional SSBR has excellent properties such as fuel efficiency characteristics and silica dispersion, which is why it has increasingly been used in tire development recently. Among the compounding characteristics, hysteresis energy loss shows good results with high functionality and high molecular weight. To evaluate the contributions of functionality and molecular weight to hysteresis, this study indirectly compared the compounding characteristics between functional SSBR and ultra-high molecular weight SSBR.
