The push for increased productivity in the tire industry was obtained by raising cure temperatures. Conventional Vulcanization (CV) was widely used for NR based tread compounds which showed a good failure property and fatigue property. although exhibited problems again t blowout, reversion and aging properties under the conditions of high temperature and loads. CV cure system consist of high sulfur and low accelerator cure system in NR based compound that exhibited high reversion rate and low blow out properties etc. Heat build-up (HBU) and wear characteristics were showed large difference along with varying cure systems under conditions of similar modulus. KA-9188 imparts excellent reversion properties and blow-out performance without falling tensile properties and process characteristics. These results suggested that CV system might be replaced with hybrid cure system in the tire industry.
