High-efficiency sulfenamide-type accelerator for natural rubber and SBR compounds.
Provides excellent scorch safety while maintaining fast cure kinetics at elevated temperatures.
Delivers consistent vulcanization performance with low volatility and minimal bloom tendency.
Compatible with conventional sulfur-cure systems and widely used in combination with MBT or CBS.
Supplied as free-flowing granules for improved dust control and precise metering in automated compounding lines.
Tire treads and sidewalls requiring balanced processing safety and crosslink density.
Industrial rubber products including conveyor belts, hoses, and vibration dampers.
Automotive non-tire components such as engine mounts and bushings.
General-purpose molded and extruded rubber goods demanding reproducible cure profiles.
Retread compounds where delayed onset of cure supports pre-vulcanization stability.
