MAJOR APPLICATIONS AND PROPERTIES
- Crystex HD OT 20 is polymeric sulfur and is insoluble in elastomers. Consequently it will retard bin scorch, prevent migration of sulfur and preserve surface tack. This is important in the manufacture of tires and other plied-up rubber goods.
- At vulcanization temperatures Crystex HD OT 20 will de-polymerize to soluble sulfur and will behave similar to "Rubber Maker's" sulfur.
- Crystex HD OT 20 is a metastable product which can revert to soluble sulfur if not stored under proper conditions.
- Reversion of Crystex HD OT 20 to soluble sulfur is also catalyzed by alkaline products. The presence of alkaline accelerators can be critical.
- Crystex HD OT 20 is a special grade with improved flowability and dispersibility.
- Crystex HD OT 20 is used in compounds containing a relatively large sulfur loading above the solubility of sulfur in the elastomer.
- Crystex HD OT 20 is non-staining and non-discoloring.
