NURCHEM TMTD-80

Tetramethylthiuram
Disulfide

C6H12N2S4
M.W. : 240
CAS : 137-26-8
EINECS : 205-286-2

PROPERTIES:
NURCHEM TMTD-80 is used as an ultra accelerator or as a booster of multi-accelerator blends with thiazoles and sulphenamides, and as a vulcanisation agent (sulphur donor) in most of the sulphur cured elastomers. It gives fast vulcanisations and therefore short processing times (scorchy). It gives an excellent vulcanisation plateau with good heat ageing and compression set resistance for use in sulphurless vulcanisation and in EV systems.
Excellent colour is obtained in carbon black-free vulcanisates. In EPDM, NURCHEM TMTD-80 is a valuable secondary accelerator. In the vulcanisation of CR with ETU, it is often used as a retarder. It is suitable for NR, SBR, IR, BR, NBR, IIR and EPDM.
NURCHEM TMTD-80 readily disperses in rubbers. It liberates 13.3 % of sulphur at vulcanisation temperatures. It is activated by aldehydeamine and guanidine accelerators. ZnO and stearic acid are required, whereas litharge tends to slow down vulcanisation.
