  • What is a vulcanization accelerator used for?
  • Application: An excellent delayed accelerator. The performance is similar as CZ with better scorch safety Widely used in NR, IR, SBR, NBR and EPDM. Can be used alone or with other vulcanization accelerators such as thiurams, guanidines and dithiocarbamates to improve the activity. Mainly used in manufacture of tires, shoes and belts.
  • What is vulcanization chemistry?
  • Vulcanization is the phenomenon of formation of cross links with rubber macromolecules. These cross links can be made up of sulfur atoms or they can have some other chemical composition if other cross linking agents are used.
  • Do halogenated PF resins vulcanize?
  • Increase the rate and state of vulcanization. The halogenated PF resin (e.g. brominated PF resin) are self activating type hence inclusion of halogen donors is not necessary when halogenated PF resins are used as vulcanizing agents. PF Resin cures are adversely affected by Amine type antioxidants and conventional rubber accelerators.
  • What is accelerated sulfur vulcanization?
  • The first step in accelerated sulfur vulcanization is the formation of ‘Accelerator-polysulfide’ by reaction of Accelerator + Zinc Oxide + Stearic acid + Sulfur. In the absence of Zinc Oxide molecule of the Type A is formed. The organic pendent group in this Type A molecule is Benzothiazole.
