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 secondaryaccelerator in CR vulcanization and EPDR vulcanization system. Used in latex products, cables and general industrial products. It's critical temperature is 80οC,so could be used as raw materials for pharmatical and dye and the test reagent for Os and Rh
