Product Description

Tetramethyl thiuram
Monosulfide

C6H12N2S3
M.W : 208
CAS : 97-74-5
EINECS : 202-605-7

PROPERTIES:
NURCHEM TMTM-80 is generally used as a secondary accelerator or as a booster for sulphenamides to achieve faster cure rates. It can be used as a booster for thiazoles and guanidines in general purpose elastomers as well. Its main application is in NBR in combination with MBT or MBTS where it acts as an activator and gives excellent balance of physical properties. In comparison with other
thiurams, it has very good processing safety, high curing activity and absolutely no discoloration. Being a monosulphide, TMTM will not cure completely without sulphur. It increases the cure rate and the torque, like other
thiurams, but with a much smaller reduction in scorch time. It is also a primary accelerator for CR together with DPG or DOTG. Especially in mercaptan-modified polychloroprene
rubbers, it may be used together with DOTG and sulphur to give very safe processing compounds. It is suitable for NR, IR, BR, SBR, NBR, IIR and EPDM. As an ultra-accelerator used together with sulphur, it is relatively high (105° C) in critical vulcanising temperatures, and fairly safe to process with. Vulcanisation is obtained at temperatures above 135 – 140° C.

Compared to a traditional EVM/EP(D)M binder, NURCHEM TMTM-80 allows :
l. Dust free products with a high level of filtration up to 38 μ.
2. Tack free products at room temperature.
3. Lower Mooney viscosity, improving quality of dispersion.
4. Scrap rate reduction thanks to filtration.
5. Wider compatibility with other elastomers.
