  • Properties: White powder. A little bitter, flammability, almost no poison. Soluble in alcohol, diethyl ether,
    acetone, cyclohexanone, tetrohydrofuran, partly soluble in all PVC plasticizers, insoluble in water and
    CS 2 . Soluble in alkali solutions and precipitation from acid solutions.
  • Application: Medium-speed vulcanization accelerator. Synergy with sulfur donor to boost vulcanization
    when used in NR and SBR. Need zinc oxide to be effective. Used as secondary accelerator in CR
    vulcanization and EPDR vulcanization system. Used in latex products, cables and general industrial
    products. Its critical temperature is 80℃, so could be used as raw materials for pharmaceutical and dye
    and the test reagent for Os and Rh.
  • Packing: In 25kgs bag.
  • Storage: Keep container tightly closed in a cool, dry and well-ventilated place, avoiding exposure of the
