Crystex™ OT 33 AS

Crystex™ OT 33 AS by Flexsys is a non-blooming vulcanizing agent for unsaturated elastomers. It is a non-staining and non-discoloring grade. It retards bin scorch, prevents migration of sulfur and preserves surface tack.

• It offers high thermal stability and dispersibility due to the presence of silica.
• Reversion of this grade to soluble sulfur is also catalyzed by alkaline products.
• At vulcanization temperatures, it will de-polymerize to soluble sulfur and behaves similarly to "Rubber Maker's" sulfur.
• Crystex™ OT 33 AS is a metastable product that can revert to soluble sulfur if not stored under proper conditions.
• It is used in compounds containing a relatively large sulfur loading above the solubility of sulfur in the elastomer.
• It is designed for tires and other plied-up rubber goods.
