  • 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.
  • Does crystextm HS OT 20 revert to soluble sulfur?
  • CrystexTM HS OT 20 is a metastable product which can revert to soluble sulfur if not stored under proper conditions. Reversion of CrystexTM HS OT 20 to soluble sulfur is also catalyzed by alkaline products. The presence of alkaline accelerators can be critical.
  • What causes crystex to revert to 'rubber maker's' sulfur?
  • Amines and other alkaline vapors can cause Crystex to revert to "Rubber Maker's" sulfur at any temperature. High temperatures will also cause Crystex to revert to "Rubber Maker's" sulfur.
  • 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.
