Abstract
Changes in the residual compression set, tensile strength and elongation at break, as well as the oxygen absorption and mass change, are evaluated during the thermal oxidation of butadiene-nitrile-based carbon black-filled rubber. Activation energies for the processes are determined. Using TGA, the activation energy of the first thermal degradation stage (87-88Â kJ/mol) corresponded to the increase in compression set. The activation energy of the second stage (116-117Â kJ/mol) corresponded to the decrease in the elongation at break and oxygen absorption. These correlations confirm that TGA can be used to predict the thermal stability of rubber.
