Stained Natural Synthetic Rubber Accelerator TT TMTD-70

Stained Natural Synthetic Rubber Accelerator TT TMTD-70

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.
