Tetramethylthiuram disulfide

C₆H₁₂N₂S₄

M.W.: 240.43

CAS: 137-26-8

EINECS: 205-286-2

PROPERTIES:

TMTD can extremely accelerate curing rate of natural and synthetic rubber and has good scorching safety. It almost does’t affect degree of cross-linking but lower scorching rate and extend total curing time when thiols or sulfenamides is added in. Aldehyde- amines and guanidines alkaline accelerators can activate TMTD. It is a primary accelerator with sulfur, a secondary accelerator with thiazoles and a vulcanizer in sulfurless vulcanization. Sulfurless or low-sulfur vulcanization can provide excellent heat aging resistance properties for vulcanizates.

DOSAGE:

Primary accelerator: 0.1-1phr with 1-3phr sulfur;

For sulfurless heat-resistant rubber compounds: 2.5-4phr with 0.5phr MBT.

TYPICAL VALUES:

Initial melting point: 141℃

Purity: Min 98%

Ash content: Max 0.3%

Heating loss content: Max 0.3%

63μm sieve residue: Max 0.5%
