CHEMICAL NAME: Tetramethyl thiuram disulfide
MOLECULAR FORMULA: C6H12N2S4
MOLECULAR WEIGHT: 240.41
CAS NO.: 137-26-8
White or light gray powder/granule. 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.
Can be used as a single accelerator, as a secondary accelerator or as a sulpur donor in most sulphur-cured elastomers. Scorchy and gives fast cure rates. Produces and excellent vulcanization plateau with good heat aging and compression set resistance insulphurless and EV cure systems. Good color retention is obtained in non-black vulcanization. A valuable secondary accelerator for EPDM. May be used as a retarder in the vulcanization of polychloroprene rubber with ETU and also be used as bactericide and pesticide.
