  • 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.
  • Why are accelerators used in vulcanizing elastomers?
  • Accelerators are added in small amounts to speed up the curing of adhesives by reducing the cure time and temperature of elastomers, particularly latex systems. The selection of an accelerator will depend on the specific vulcanizing system and curing properties.
  • 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.
  • How do I select a vulcanizing accelerator?
  • The selection of an accelerator will depend on the specific vulcanizing system and curing properties. Explore the classification of accelerators, the checklist to select the right accelerator based on the specific vulcanizing systems and curing properties.
  • Is ZBED a good ultra-accelerator for vulcanization of butyl rubber extrusions?
  • However, ZBED is a typical ultra-accelerator at normal curing temperatures. It is also useful as a seco nuous vulcanization of butyl rubber extrusions.SNN Zn-SSSN ZnSS S SNZDBCX or zinc N, N-di-n-butyldithio-carbamate/di-n-b ylamine complex is an ultra-accelerator which is active at room temperature. It can be
  • What determines vulcanization rate?
  • The accelerator determines the rate of vulcanization, whereas the accelerator to sulfur ratio dictates the efficiency of vulcanization and, in turn, the thermal stability of the resulting vulcanizate. Certain elastomers such as chloroprene can be vulcanized by the action of metal oxides such as zinc oxide as well as sulfur.
