Presentation

Sustainable aminic substances in silica-filled compounds

This presentation introduces a novel aminic accelerator for state-of-the-art passenger car tires based on SBR/BR compounds with high silica content. Typically, aminic accelerators are used to enhance silica dispersion, activate silanization and accelerate sulfur vulcanization. The new substance presented offers improved safety and a more sustainable profile compared to currently used chemicals. It also delivers enhanced silica dispersion and superior dynamic mechanical properties, making it a promising alternative for the tire industry. This innovation aims to contribute to the development of more efficient and environmentally friendly tire manufacturing processes.
