Poly- and disulfidic silanes like TESPT (Si 69) or TESPD (Si 266) are state-of-the-art in silica filled passenger car tread compounds as effective coupling agents1,2,3. There is an increasing interest for reducing the fuel consumption of vehicles because oil prices are already on a high level and rising steadily. One possible way for fuel saving is the reduction of the rolling resistance of tires. Additionally new approaching legislational restrictions lead the interest also to lower emissions of carbon dioxide and VOCs (Volatile Organic Compounds) during tire production and tire lifetime. The new silane VP Si 363 combines a significant increase in tire performance by reducing rolling resistance by more than 10 % with the solution for the new ecological needs by cutting the ethanol emission by 80 %.
