  • What is HS ot20 soluble sulfur used for?
  • HS OT20 Insoluble Sulfur is used as a vulcanizing agent for rubber compounds. Use of insoluble sulfur prevents migration (bloom) of sulfur from uncured rubber compounds stock. This allows good building tack and fewer flow lines in compression cured parts.
  • How does insoluble sulfur affect the performance of rubber compounds?
  • At 130°C, there is no significant dif-ference in the rate of migration between insoluble and soluble sulfur. The use of insoluble sulfur can pre-vent sulfur migration between adjacent rubber compounds thus avoiding varia-tion in compound performance. Table IX. Processing and curing properties. Effect of HD OT 20.
  • What is insoluble sulfur?
  • adhesion. Insoluble sulfur, so called because it is insoluble in rubber, is a very high molec-ular weight polymeric form of sulfur. It mainly is used as a replacement for ordi-nary sulfur (the soluble form of sulfur) to prevent sulfur bloom in unvulcanized rubber compounds.
  • Does insoluble sulfur prevent vulcanization?
  • The principle use of insoluble sulfur is to eliminate sulfur bloom on rubber compound prior to vulcanization, but ad-ditional benefits can be found from pre-venting migration of sulfur between rubber compounds in contact with each other.
  • How does insoluble sulfur affect cured parts?
  • Use of insoluble sulfur prevents migration (bloom) of sulfur from uncured rubber compounds stock. This allows good building tack and fewer flow lines in compression cured parts. Insoluble sulfur slowly converts to standard sulfur above 220°F (or very rapidly at curing temperatures) so there is no effect on sulfur migration in cured parts.
  • What is soluble sulfur used for?
  • It mainly is used as a replacement for ordi-nary sulfur (the soluble form of sulfur) to prevent sulfur bloom in unvulcanized rubber compounds. Insoluble sulfur is formed by the rapid cooling of molten sulfur or by precipitation from aqueous solution of sulfur derived from acids.
