Studies have been done to explore possibilities of low temperature curing in typical natural rubber based compounds. Combination of fast accelerators together with amine activation has been used in this approach. It has been found that it is possible to lower the vulcanization temperature as low as 60 °C and still obtain sufficient cure. The combination of ZMBT/ZDC/Amine provides a best compromise with regard to cure kinetics and ultimate properties. In consideration with N-Nitrosamine safe system, the combination of ZBEC/ZMBT/DPG provides an optimum solution. A three variable experimental design was executed to optimize the recipe comprising of ZBEC/ZMBT/DPG systems.
