- 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
packaged product to direct sunlight.
