Properties: White powder. The density is 1.32. 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 CS2. Soluble in alkali solutions and precipitation from acid solutions.
Application: Medium-speed vulcanization accelerator. Synergises 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. It’s critical temperature is 80℃,so could be used as raw materials for pharmatical and dye and the test reagent for Os and Rh.
Packaging: 25kg plastic woven bag, paper with plastic film bag, kraft paper bag.
Storage: The product should be stored in the dry and cooling place with good ventilation, avoiding exposure of the packaged product to direct sunlight The validity is 1 year.
