Dimethyl thiuram disulfide

Dimethyl thiuram disulfide, commonly known as Thiram or sold under trade names such as Arasan and AATIRAM, is an organosulfur compound registered under CAS 137-26-8 and EC 205-286-2. It carries no assigned E-code and is classified within the agrochemical category with the HS code 29303000.

In rubber manufacturing, Thiram functions as a primary vulcanization accelerator, promoting sulfur crosslinking between polymer chains to improve elasticity and durability. In agriculture, it acts as a broad-spectrum fungicide by inhibiting spore germination through disruption of cellular enzyme activity. It also serves as an antimicrobial preservative in certain industrial formulations.

Thiram is supplied as a crystalline solid, with commercial grades available in technical and agricultural specifications. It falls under REACH registration requirements for EU procurement and must be handled in accordance with applicable pesticide regulations. Standard packaging includes multi-wall bags and fiber drums suited for bulk industrial orders.
