  • What is accelerator DPTT?
  • Accelerator DPTT is a non-discoloring and non-staining accelerator. It is a very active sulfur-bearing accelerator and contains approximately 25% available sulfur. DPTT imparts unusually good heat resistance to sulfurless compounds and may be used as a primary accelerator for Hypalon and Butyl as well as an excellent secondary accelerator for EPDM.
  • What are accelerators used for in rubber vulcanization?
  • Accelerator, in the rubber industry, is added with a curing agent to speed the vulcanization. Accelerators contain sulfur and nitrogen like derivatives of benzothiazole and thiocarbanilides. The popular accelerators are sulfenamides (as a delayed-action accelerators), thiazoles, thiuram sulfides, dithocarbamates and guanidines.
  • Which accelerators are compatible with vulcanizates?
  • All common primary and secondary accelerators, activators and retarders are compatible. Standard sulfur system: >1 phr sulfur/insoluble sulfur, usually without sulfur donor. Additionally 0.2–1.0 phr sulfur donor to improve the physical properties of the vulcanizates
  • Is accelerator DPTT the same as akrochem?
  • It is both, as all products of this type are a blend of the two forms. Akrochem DPTT may cause skin irritation in some individuals. Avoid prolonged or repeated contact with skin. Avoid breathing dust or vapor. Use with adequate ventilation. Accelerator DPTT is also available as Akroform® DPTT-70/EPR/P (pellets).
  • What is the function of mercapto sulphenamide in rubber vulcanization?
  • It also functions as sulfur donor for vulcanization with low or no free sulfur. It causes very rapid and scorch-safe vulcanization of rubber along with good processing safety. It acts as activating secondary accelerator, when combine with other mercapto- or sulphenamide-type-accelerators.
  • What is vulcanization with vulcuren®?
  • The heat stability of passenger tire tread compounds with Vulcuren® can be improved in comparison to compounds with a standard curing system. Vulcanization with Vulcuren® shows fast curing and a stable plateau. Physical as well as viscoelastic properties of the vulcanizates can be easily achieved.
