TMTD(TT)
Chemical Name: Tetramethyl thiuram disulfide
Molecular Formula: C6H12N2S4
Molecular Weight: 240.41
CAS NO: 137-26-8
Properties: White or light gray powder (granule). The density is 1.29. Soluble in benzene, acetone, chloroform, CS2 partly soluble in alcohol, diethyl ether, CCI4 insoluble in water, gasoline and alkali with lower concentration. Meeting hot water becomes to dimethyl ammonium and CS2. Be sensitive to skin and peogaster
Application: Can be used as a single accelerator, as a secondary accelerator or as a sulphur donor in most sulphur-cured elastomers. Scorchy and gives fast cure rates. Produces an excellent vulcanisation plateau with good heat aging and compression set resistance in sulphurless and EV cure systems Good color retention is obtained in non-black vulcanisation. A valuable secondary accelerator for EPDM. May be used as a retarder in the vulcanisation of polychloroprene rubber with Willing ETU and also be used as bactericide and pesticide
