  • 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 HD OT 20 revert to soluble sulfur?
  • CrystexTM HD OT 20 is a metastable product which can revert to soluble sulfur if not stored under proper conditions. Reversion of CrystexTM HD OT 20 to soluble sulfur is also catalyzed by alkaline products. The presence of alkaline accelerators can be critical. CrystexTM HD OT 20 is a special grade with improved flowability and dispersibility.
  • What causes crystextm to revert to 'rubber maker's' sulfur?
  • Amines and other alkaline vapors can cause CrystexTM to revert to "Rubber Maker's" sulfur at any temperature. High temperatures will also cause Crystex revert to "Rubber Maker's" sulfur. When stored in closed containers below 20°C the reversion rate is less than 1%/year. Reversion of CrystexTM could result in sulfur bloom of uncured rubber.
