Investigation and improvement of the scorch behavior of silica‐filled solution styrene‐butadiene rubber compound

Effects of different silane coupling agents on scorch time of silica‐filled solution styrene‐butadiene rubber compounds were studied. The flocculation of silica at high temperature, which was characterized by rubber processing analyzer (RPA) and transmission electron microscope (TEM), has been proved to be an important factor affecting the scorch time of the compounds. In order to prolong the scorch time, the hybrid silane technology, that is,...
