Crystex™ HD OT 20

Supplied byFlexsys- Last Updated on Mar 18, 2026

Crystex™ HD OT 20 by Flexsys is a non-blooming vulcanizing agent for unsaturated elastomers. It retards bin scorch, prevents migration of sulfur and preserves surface tack. It offers improved flowability, dispersibility, non-staining and non-discoloring properties.
  • At vulcanization temperatures, it de-polymerizes to soluble sulfur and behaves similarly to "Rubber Maker's" sulfur.
  • It is a metastable product that can revert to soluble sulfur if not stored under proper conditions.
  • Crystex™ HD OT 20 is designed for the manufacture of tires and other plied-up rubber goods.
  • It complies with TCSI, TSCA, AICS, DSL, ENCS, ISHL, KECI, PICCS and IECSC.
