Properties & Features:Insoluble sulfur (IS-HS) OT20 is a non-blooming vulcanizing agent for unsaturated rubbers.It is insoluble in rubbers, will retard bin scorch, prevent migration of sulfur and preserve surface tack. At vulcanization temperature Insoluble sulfur (IS-HS) OT20 will depolymerize to solube sulfur and will behave similar to "rubber maker's" sulfur.
Insoluble sulphur is a non-toxic, inflammable yellow powder, it is allotrope of common sulphur, it is linear polymer molecular polymerized by a large number of sulphur atoms .Insoluble sulphur do not dissolve in dioxide sulphur and other solvents,do not dissolve in rubber, so it is called insoluble sulphur or polymeric sulphur and chemical
