Nowaday,s it is mandatory to find sustainable solutions to tire production, such as recycling carbon black (CB). Of course, recycling of CB implies studying its effects on tire properties. DMA measures the modulus and the damping ability of tires and it is a key tool to understand the behavior of tire performance. Studying rubber at large strain (LAOS) leads to better understanding of polymer-chain interactions. This study investigates the hysteresis curves on two rubbers: one filled with CB and another with recycled CB. The primary goal is to differentiate between these materials and assess their suitability for the tire industry.

• DMA principle
• Large amplitude oscillatory shear
• Difference in viscoelastic properties between rubbers filled with carbon black and rubbers filled with recycled black carbon
