Eastman Crystex™ HD OT 20 Vulcanizing Agent
Categories:	Other Engineering Material
Material Notes:	CAS No. Polymeric sulfur: 90 35-99-8; Rhombic sulfur: 7704-34-9 Chemical name: Polymeric sulfur. Crystex™ HD OT 20 is a non-blooming vulcanizing agent for unsaturated elastomers. 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.
