The partial replacement of the silane coupling agent, TESPT by Sulfron 3000 in 'green tire' compounds has been studied. It was demonstrated that reducing the level of TESPT has negative consequences on the properties such as stress-strain, tear, hysteresis etc. However, incorporating Sulfron 3000 into the compounds containing reduced level of TESPT nullifies all the effects providing even better performance. Network density data indicates that Sulfron 3000 provides no changes in the network density and distribution of the crosslink types. Above all, laboratory data indicate that it is possible to optimise the level of TESPT to reduce compound cost with no detrimental effect on product performance. It was demonstrated that application of Sulfron in a truck/bus tread compound reduces significantly compound hysteresis translating into better rolling resistance or fuel economy. Tire test data showed a significant improvement in rolling resistance, durability and wear characteristics. Mechanistic view was provided to explain the advantages. Sulfron 3001 appeared to be the product of choice for NR-based compounds. The reduction in tan delta is almost double compared to that obtained with Sulfron 3000. Sulfron 3001 can be mixed at all temperatures whereas Sulfron 3000 has to be mixed at temperatures > 160 deg C or compounds have to be cured within 3 days after mixing in order to get the improved performance with this compounding ingredient.
