Commercial insoluble sulfur products contain a stabilizer to reduce this tendency. When insoluble sulfur is mixed in a rubber compound, it exists as more or less discreet particles of varying size in the rubber phase. Above about 118°C substantial reversion to the soluble sulfur form occurs with resulting sulfur bloom.
high temperature stable insoluble sulfur is60 rubber tube in. Insoluble sulfur (IS) is a type of sulfur polymer, which is insoluble in CS2 and is a good rubber vulcanizing agent [1-4]. There are two types of IS, oil-filled and non-oil-filled.

Synthetic Rubber an overview ScienceDirect Topics
Synthetic rubber (cis -1,4-polyisoprene) can be obtained via radical chain polymerization of the monomer (isoprene). It was the isolation of this chemical during the pyrolysis of natural rubber that provided the key to identifying the building block. The evolution of the catalysts occurs for 70 years when Ziegler-type catalyst was used (1955).
