Tetrabenzyl thiuram
Disulphide
C30H28N2S4
M.W : 544
CAS : 10591-85-2
EINECS : 404-310-0
PROPERTIES:
NURCHEM TBzTD-70 is a fast primary thiuram accelerator for NR, IR, BR,SBR and NBR. It used as a secondary accelerator too. In NR, in association with CBS, it is better in reversion and heat build up than TMTD and it has a longer
scorch time. In EPDM, it is a good booster when is combining with other accelerators In mercaptan modified CR, it is a scorch retarder when it is used with ETU. In vulcanisation, NURCHEM TBzTD-70 shows a good dispersion and a good degree of processing safety in
comparison with TMTD.
APPLICATIONS:
Tires, buffers, conveyor belting, seals, hoses, profiles, footwear, cable sheathing, insulation, etc.

Compared to a traditional EVM/EP(D)M binder, NURCHEM TBzTD-70 allows :
l Dust free products with a high level of filtration up to 38 μ.
l Tack free products at room temperature.
l Lower Mooney viscosity, improving quality of dispersion.
l Scrap rate reduction thanks to filtration.
l Wider compatibility with other elastomers.
