Colloidal properties of different carbon black (CB) grades represented by their structure and specific surface area were characterized before and after pyrolysis. Additionally, rubber compounds produced with these fillers were investigated by Fourier Transform (FT) Rheology, since the nonlinear, rheological behavior of filled elastomers under specific conditions is associated with the filler polymer interaction.

In recent years, the accelerated growth in the world’s population and the global economy has led to a rapid development of the automobile industry and a remarkable increase of vehicle numbers worldwide resulting in environmental discussions and public concerns over End of Life Tire (ELT) disposal.
