New tailored ULTRASIL HD silica for modern tire applications

Following the general trend in the tire industry for sustainable and highly reinforcing silica/silane solutions, Evonik introduces a new member of the highly dispersible ULTRASIL family. Specially dedicated to high abrasion resistance and simultaneously low rolling resistance, the particle size distribution in the nanometer range has been optimized to meet current market expectations. The new grade has already been transferred to several Evonik plants worldwide and tested successfully in regular tire production facilities. In this way, the new ULTRASIL will be produced with the same high quality that customers trust in, fulfilling the maxim of global production combined with regional customer proximity.
