  • 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 vulcanization activator carries more dispersed Zn units?
  • The use of activators also bearing more dispersed Zn units will be described: nanosized ZnO particles; zinc complexes; zinc loaded clays; ZnO nanoparticles (NPs) dispersed onto different supports; and, the ZnO/SiO 2 double function filler, simultaneously reinforcing filler and vulcanization activator. 2. Rubber Vulcanization
  • Is ZnO a good activator for rubber vulcanization?
  • Actually, CdO showed better activating behavior in rubber vulcanization [ 38 ], but its higher toxicity precludes its use for substituting ZnO. Therefore, at the moment, ZnO still remains the most efficient activator of rubber vulcanization.
  • How to improve the efficiency of sulfur vulcanization reaction in rubber industry?
  • Multiple requests from the same IP address are counted as one view. The efficiency of sulfur vulcanization reaction in rubber industry is generally improved thanks to the combined use of accelerators (as sulphenamides), activators (inorganic oxides), and co-activators (fatty acids).
