Tetramethylthiuram Disulfide

Tetramethylthiuram Disulfide (CAS 137-26-8), commercially known as Thiram and abbreviated TMTD, is an organosulfur compound used as a rubber vulcanization accelerator, fungicide, and industrial biocide.

Where is Tetramethylthiuram Disulfide used?

• Rubber and tire manufacturing: primary or secondary vulcanization accelerator
• Agriculture: active ingredient in seed treatment and foliar fungicide formulations
• Latex preservation and polymer stabilization: biocide for aqueous rubber dispersions
• Specialty chemical syntheses: catalyst precursor where controlled sulfur donation is required
• It enables efficient crosslinking at lower temperatures and improves aging resistance in finished rubber goods.

Commercial specifications

• Purity typically ranges from 95% to 98%+.
• Masterbatch forms suited for rubber compounding to ensure uniform distribution.
