Tire tread compounds typically consist of blends of rubbers with SSBR a key component for PCR and LT tires. Global regulations, tire labeling, strict OE requirements, electrification and customer awareness are driving the developments for next generation tires and subsequently, new and improved raw materials. For SSBR, anionic polymerisation imparts a unique versatility with regard to microstructure, polymer architecture, and functionalization. Functionalized SSBRs have been developed since the 1980s to improve the interaction of SSBR with carbon black filler used for tire tread compounds. This improved interaction results in a reduced tire rolling resistance via a better filler dispersion and via the attachment of the polymer chain ends to the filler. With the advent of green tire technology, the focus of SSBR functionalization shifted to functional groups interacting and reacting with silica. Targeted functionalization of SSBR leads to a significant improvement for tire tread compounds, primarily in their rolling resistance and abrasion resistance, without having a negative impact on their wet grip behaviour. This presentation will highlight two new functionalized SSBR grades developed by ARLANXEO.
