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. Sulfur forms cross-linking bridges between sections of polymer chains which affects the mechanical and electronic properties. Many products are made with vulcanized rubber, including tires, shoe soles, hoses, and conveyor belts. The term vulcanization is derived from Vulcan, the Roman god of fire.

dbo:abstract
  • La vulcanización con azufre es un proceso químico para convertir caucho natural o polímeros relacionados en materiales de una variedad de dureza, elasticidad y durabilidad mecánica calentándolos con azufre​ u otros curativos o aceleradores equivalentes.​ El azufre forma puentes de reticulación entre secciones de cadenas de polímeros que afectan las propiedades mecánicas y electrónicas. Muchos productos están hechos con caucho vulcanizado, incluidos neumáticos, suelas de zapatos, mangueras y cintas transportadoras. El término se deriva de Vulcan, el dios romano del fuego. Los principales polímeros sometidos a vulcanización con azufre son el poliisopreno (caucho natural, NR), el caucho de polibutadieno (BR) y el caucho de estireno-butadieno (SBR), todos ricos en enlaces insaturados.​ También se pueden vulcanizar varios otros cauchos especiales, como (NBR), caucho de butilo (IIR) y caucho EPDM. La vulcanización, al igual que el curado de otros polímeros termoendurecibles, es generalmente irreversible. Sin embargo, importantes esfuerzos se han centrado en desarrollar procesos de "des-vulcanización" para el reciclaje de desechos de caucho. (es)
  • 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. Sulfur forms cross-linking bridges between sections of polymer chains which affects the mechanical and electronic properties. Many products are made with vulcanized rubber, including tires, shoe soles, hoses, and conveyor belts. 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). All of these materials contain alkene groups adjacent to methylene groups. Other specialty rubbers may also be vulcanized, such as nitrile rubber (NBR) and butyl rubber (IIR). Vulcanization, in common with the curing of other thermosetting polymers, is generally irreversible. Efforts have focussed on developing de-vulcanization (see tire recycling) processes for recycling of rubber waste but with little success. (en)
