  • Can MgO-only vulcanize rubber?
  • In particular, binary accelerators, one of which contains zinc ions, can show synergistic effects on the vulcanization properties [ 42 ]. Hence, it is believed that MgO-only can, with some difficulty, replace the ZnO by using a single accelerator for the vulcanization of rubber.
  • 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.
  • 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 an efficient vulcanization system?
  • Moreover, a high accelerator to low sulfur ratio that is known as an efficient vulcanization system (EV), which can produce higher mono and disulfide cross-links with better thermal stability than other vulcanizing systems such as conventional vulcanization (CV) and semi-efficient vulcanization (SEV), is considered.
