Sulfonamide |
An aftereffective quick vulcanization accelerant. Vulcanized rubber manufactured from such accelerant has wide vulcanization smoothness and rubber is not readily overvulcanized. Normally, the burning time is extended sequentially according to the product. | | Brand name | Chemical name | CZ or CBS | N-Cyclohexylbenzothiazole sulfenamide | NS or TBBS | N-t-butyl benzo- thiazole sulfenamide | NOBS or MBS | N-oxydiethylene-2-benzo-thiazole sulfenamide | DZ or DCBS | N,N'- Dicyclohexylbenzothiazole-2-sulfenamide |
