- 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.
- Will crystextm HS OT 20 de-polymerize to soluble sulfur?
- At vulcanization temperatures CrystexTM HS OT 20 will de-polymerize to soluble sulfur and will behave similar to "Rubber Maker's" sulfur. CrystexTM HS OT 20 is a metastable product which can revert to soluble sulfur if not stored under proper conditions.
- 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. CrystexTM HS OT 20 is a special grade with high thermal stability.
- 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. When stored in closed containers below 20°C the reversion rate is less than 1%/year. Reversion of Crystex could result in sulfur bloom of uncured rubber.
