The present work is focused on the role of CB surface activity in the influence on the vulcanization reaction. To study this effect two carbon black grades, N-774 and Durex-O, of high surface activity (more than normal CB grades) and low surface area have been chosen. IGC is used to determine both disperse and polar components of the surface activity in order to establish more accurately which one is more relevant concerning to breaking down the accelerator (CBS). The results show that in presence of carbon blacks, the accelerator decomposition occurs faster. In this sense, the polar component of surface activity seems to play the most important role in such decomposition. Their low surface area mainly governs vulcanization intermediates adsorption on their surface. It can be concluded that although the accelerator decomposition is directly related with CB grade, the specific surface area of CBs can not explain by itself this behavior.
