The sulfenamide accelerator is a derivative of the promoter M, which should be a thiazole, but because of its unique aftereffect, it has developed rapidly in recent years and is classified as a separate class.
The aftereffect of the accelerator usually means that the starting point of vulcanization is slow, the scorch time is long, and the vulcanization activity at the vulcanization temperature
Large, fast curing speed. The sulfenamide accelerator is currently the fastest growing accelerator. Along with the development of synthetic rubber and its extensive application in tires, furnace black with good reinforcing performance replaces channel black, and the rubber added to furnace black is easy to scorch. In addition, in recent years, the processing technology of rubber has developed toward a high temperature and rapid direction, and the phenomenon of early vulcanization of the rubber compound during processing is more prominent. In order to eliminate this drawback, the application of the after-effect sulfenamide accelerator is affected.
