  • What is vulcanizing agent?
  • Vulcanizing agent is the most important ingredient in this system as it is used to strengthen the rubber compound properties through the vulcanization process. Normally, this process is conducted by heating the mixture of raw rubber with vulcanizing agents at specific vulcanization time in a pressurized mold.
  • 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 vulcanization system?
  • The main function of the vulcanization system is to convert the physical properties of raw rubber from tacky into non-tacky and elastic rubber. The vulcanizing system needs three important ingredients for the system to function efficiently, which are the vulcanizing agents, accelerator, and activator.
  • Which materials can be used as vulcanization agents?
  • Organic accelerators and similar compounds that release sulfur at vulcanization temperatures can also be used as vulcanization agents. These materials are added in 3–5 phr and form monosulfidic linkages with excellent heat resistance. The generally used materials are shown in Table 1.17. Table 1.17.
