Oil-Treated Insoluble Sulfur IS-HS-OT20
CAS Number: 7704-34-9
Oil-Treated Insoluble Sulfur IS-HS-OT20 is an insoluble sulfur grade surface-treated with 20% naphthenic or process oil to suppress dust and improve dispersibility in rubber compounds. The oil coating reduces the risk of static charging during handling and facilitates uniform incorporation into rubber matrices on open mills and internal mixers. It is the preferred form for automated tire manufacturing lines.
