Abstract The effects of the different fillers i.e., china clay, light magnesium carbonate, Pliolite S 6 E, and ebonite dust, on the exothermic hard rubber reaction has been studied with the help of differential thermal analysis. The data for heat evolution show some unexpected features in that china clay, a more or less inert filler, lowers heat evolution. The behavior of magnesium carbonate also can not be fully explained. Attempts have been made to explain the data for Pliolite S 6 E and ebonite dust on the basis of their composition and effects of the individual components on heat of reaction. The differences in initiation temperature and slope values have been explained.
