Fast curing rubber compounds are commonly required in high-volume production environments where shorter cycle times and higher productivity are essential. Rubber accelerators used for fast curing applications help speed up the vulcanization process while still providing acceptable scorch safety and uniform crosslinking. Without suitable accelerators, rubber compounds may require longer curing times, leading to lower output and higher energy consumption.
Accelerators such as ZDBC, ZDEC, and TMTD are widely used for fast curing rubber formulations. These accelerators promote rapid sulphur crosslink formation, resulting in quicker vulcanization and efficient processing. Depending on application needs, fast accelerators may also be combined with secondary accelerators to balance curing speed and processing safety.
Supporting additives like Zinc Oxide enhance accelerator activity, while antioxidants such as TMQ and TDQ protect rubber from heat and oxidative degradation. Reliable-quality accelerators and additives help manufacturers maintain consistent curing behavior, reduce cycle time variations, and achieve uniform physical properties in finished products. This is especially important in the production of molded goods, extruded profiles, and other rubber components where productivity and consistency are critical.
