Insoluble Sulfur IS-HS (Rubber Grade)
Insoluble Sulfur IS-HS is a high-stability polymeric form of sulfur used as the primary vulcanizing agent in tire manufacturing. Unlike soluble sulfur, it prevents bloom migration to the rubber surface before vulcanization, ensuring excellent ply adhesion and uniform crosslink distribution. It is the industry standard for steel-cord and textile-cord tire compounds.
