The mixing of Sulfron 3001 in carbon black compounds is described in this paper. The temperature-time profile of mixing between Sulfron and carbon black plays a critical role in realizing the positive effect of Sulfron on hysteresis characteristics. It has been shown that at a mixing temperature ≤140°C, there is almost no reaction between carbon black and Sulfron 3001. On the other hand, temperature above 165°C of mixing temperature, processing problems could occur because of side reactions of Sulfron 3001 on rubber. Two mixing sequences are described that provides the best results. It has been found that a temperature between 150-165°C is required to get the reaction of Sulfron 3001 and carbon black started. The time plays an important role too. It is demonstrated that time required is about 2-2,5 minutes after Sulfron and carbon blacks are added to the rubber mixes after the desired temperature (150-165°C) is reached.
