  • What vulcanizing agent is used in rubber?
  • Elemental sulfur is the predominant vulcanizing agent for general-purpose rubbers. It is used in combination with one or more accelerators and an activator system comprising zinc oxide and a fatty acid (normally stearic acid). The most popular accelerators are delayed-action sulfenamides, thiazoles, thiuram sulfides, dithocarbamates and guanidines.
  • What is DPTT used for?
  • 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. It can also be used as a vulcanizing agent for heat resistant latex.
  • Which elastomers can be vulcanized?
  • Certain elastomers such as chloroprene can be vulcanized by the action of metal oxides such as zinc oxide as well as sulfur. As a result, several of the same accelerators that are used with sulfur vulcanization systems can be used with zinc oxide/neoprene systems. Because there are so many, accelerators are generally classified by chemical family.
  • 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.
