Rubber Compound for Tires — Decomposition

Besides the plasticizer portion (ca. 7%), the first elastomer components during the Decomposition reactionA decomposition reaction is a thermally induced reaction of a chemical compound forming solid and/or gaseous products. decomposition of a rubber compound are derived at 383°C (38%) and the second at 448°C (31%).

The carbon black portion is calculated at 20% and the ash content at 4%. The position of the peak temperatures of the derived TGA curves (DTG) show that the compound is a carbon black-filled NR/SBR rubber blend. (measurement with TG 209 F1 Libra®®)
