Characteristics

  • A dedicated accelerator for chloroprene rubber (especially W type), epichlorohydrin rubber, chlorinated polyethylene, and other chlorinated synthetic rubbers.
  • Can be used as an antiozonant for natural rubber and synthetic rubber.
  • Functions as an auxiliary brightener for copper sulfate, assisting in the treatment of waste water from copper ore leaching.
  • Offers safe handling during vulcanization,easy dispersion, no discoloration, and low blooming tendency.
  • Accelerates vulcanization, enhances the heat resistance of the rubber compound and improves the tensile stress and permanent compression set of the vulcanized product.
  • Compared with ETU,this product exhibits shorter scorch time and faster vulcanization speed,while maintaining good curing plateau characteristics. When used at higher dosages, it enables high-temperature and high-speed vulcanization,suitable for the making it particularly continuous vulcanization of extruded products.
  • Has an activating effect on thiazole and sulfenamide accelerators.
  • Usage level: 0.25-1 phr.
