  • Why is insoluble sulfur a vulcanizing agent?
  • Insoluble sulfur is important in the rubber industry as a vulcanizing agent since, when it is used, it can prevent rubber compounds from blooming during storage or during a production process without any adverse impact on the vulcanization process.
  • What is sulfur vulcanization?
  • Sulfur vulcanization is a chemical process for converting natural rubber or related polymers into materials of varying hardness, elasticity, and mechanical durability by heating them with sulfur or sulfur-containing compounds.
  • Does sulfur vulcanize polyolefins?
  • Short crosslinks, possessing lower numbers of sulfur atoms, give the rubber better resistance to heat and weathering. Longer crosslinks, with higher numbers of sulfur atoms, give the rubber improved physical durability and tensile strength. Sulfur, by itself, is a slow vulcanizing agent and does not vulcanize synthetic polyolefins.
  • What polymers are vulcanized?
  • The term vulcanization is derived from Vulcan, the Roman god of fire. The main polymers subjected to sulfur vulcanization are polyisoprene (natural rubber, NR), polybutadiene rubber (BR) and styrene-butadiene rubber (SBR), and ethylene propylene diene monomer rubber (EPDM rubber).
