Characteristics

  • A specialized accelerator for chlorinated synthetic rubbers such as neoprene(especially W-type),epichlorohydrin rubber, and chlorinated polyethylene; it can also be used as an antioxidant for natural rubber and synthetic rubber; it can also function as an auxiliary brightener for copper sulfate, aiding in the treatment of waste water from the leaching of copper-bearing ores.
  • Offers good processing safety during vulcanization, is easy to disperse, does not cause discoloration, and is not prone to blooming.
  • Suitable for predispersion processing,providing stable extrusion efficiency,excellent masterbatch dispersibility,and uniform appearance with minimal color difference.
  • It accelerates vulcanization at typical curing temperatures(above121℃),(enhance the heat resistance of the compound, and improves the tensile stress and permanent compression set of the vulcanized products.
  • Usage level: 0.1-2.0 phr.
