Nouryon will introduce a new peroxide‑based compounding concept for natural rubber and carbon black at the 26th Tire Technology Expo. This innovation will be presented publicly for the first time in a session titled “Novelty in Payne Effect Reduction: Using Organic Peroxides in Natural Rubber/Carbon Black Compounds”.
Silica–silane systems currently dominate low rolling‑resistance tire technology, while carbon black–filled compounds have traditionally been limited by challenges in controlling filler–filler interactions. In this work, a patented peroxide‑based compounding concept for natural rubber (NR)/carbon black (CB) formulations is presented, specifically targeting reduction of the Payne effect and hysteresis, to reduce rolling resistance. By reactive compounding small amounts (<1 wt%) of selected organic peroxides in combination with stabilizers during the masterbatch mixing stage significant modification of the rubber–filler interface is achieved.
Key points of the presentation are as follows:
- Serious reduction of Payne effect of NR/CB compounds after reactive compounding with organic peroxides
- The resulting compounds show markedly improved carbon black dispersion, a reduction in filler network, and enhanced rubber–filler interaction.
- Dynamic mechanical analysis demonstrates a significant reduction in tan δ at 70 °C, indicating substantial hysteresis reduction and strong potential for rolling‑resistance improvement.
- The concept offers a practical and scalable pathway toward next‑generation low rolling‑resistance tires
Come and explore the innovation that delivers clear, measurable performance gains.
