  • Since the first introduction in the 1990s green tire technology has developed rapidly. The main driver are e-mobility, the increasing demand for the reduction of fuel consumption and CO2 emissions and new labelling liabilities. Major lever for the development has been the continuous improvement of the silica/silane technology. Typically, low molecular weight functional silanes are used to improve the dispersion of silica enabling for the optimization of key performance indicators such as rolling resistance, wet grip and abrasion resistance. More recently functionalized rubbers have raised the attention of the rubber community as alternative and complementary technology. Based on the increasing ecologic & economic challenges further improvement of the technology is one of the most important tasks for the tire industry. In this contribution we present silane functionalized liquid rubbers as a (new) class of materials. These hybrid materials exhibit an alternative binding opportunity via the unsaturated polymer backbone and offer additional opportunities for partial oil replacement. In the present study we will introduce silane functionalized liquid rubbers and their benefits in typical passenger car and truck tire tread compounds. The contribution includes in-rubber data for the most common rubber combinations (SSBR/BR, NR) focusing on the effects on characteristic processing and performance indicators.
