n the processing of raw rubber, sulfur is added
for shape retention. To enhance the efficiency
of curing and the vulcanization process,
chemical curatives known as accelerators
and activators are frequently used. However,
excessive use of chemical curatives has raised
major concerns about their adverse impact on human
and animal health as well as on the environment. In
most tire compounds, sulfenamide accelerators and
zinc oxide are used in combination with sulfur to
achieve efficient vulcanization. Since these chemicals
are essential to improve the curing process, it is likely
that their use in tire compounds will continue for
some time. Therefore, their use must be lowered
without compromising the cure properties and
adversely affecting the cure cycle of tire compounds. ....
