***Typical Properties
Non-rised yellow powder with slight odor, non-toxic. HD OT20 is not stable and At vulcanization temperatures it will de-polymerize to soluble sulfur. HD OT20 is insoluble in CS2 and water.
***Recommended Applications
HD OT20 is a non-blooming vulcanizing agent for unsaturated. It is polymeric sulfur and is insoluble in elastomers. So 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.HD OT20 is a special grade with high thermal stability dispersibility.
It is used in compounds containing a relatively large sulfur loading above the solubility of sulfur in the elastomer.
***Handling and Storage recommendations
HD OT20 should be stored in a well-ventilated area below 30ºC, Avoiding exposure of the packaged product exposure to direct sunlight. Do not store near by alkaline.    
12 months with the common storing condition. Recommend use of date is within 6 months.
