It is a highly active aftereffect accelerator with excellent scorch resistance, safe processing and short vulcanization time. When the vulcanization temperature is above 138 ℃, the promoting effect is very strong. Often cooperate with TMTD or other basic accelerators to form a second accelerator. Alkaline accelerators such as thiuram and disulfide carbamates can enhance their activity. It is mainly used for manufacturing industrial rubber products such as tires, rubber hoses, rubber shoes and cables.
