Dimacit TMTD-PDR is a valuable secondary accelerator.
Dimacit TMTD-PDR is recommended for use in soft compounds due to dispersability.
Dimacit TMTD-PDR is non-staining and non-discoloring.
CAS Number: 137-26-8
Chemical name: tetramethylthiuram disulphide
Molecular Formula: C6H12N2S4
Molecular Weight: 240.4
Applications of Dimacit TMTD-PDR:
Rubber and plastic additives
Rubber modification
Product Description of Dimacit TMTD-PDR:
This product is designed for the rubber industry.
Two grades are available: pdr; pdr-d.
All grades are white to off white.
Dimacit TMTD-PDR offers fast vulcanization and gives an excellent vulcanization plateau with good heat aging and compression set resistance when used in sulfurless vulcanization systems and EV systems.
In mercaptan modified polychloroprene cured with ETU, Dimacit TMTD-PDR acts as a scorch retarder without affecting the cure speed.
Dimacit TMTD-PDR's excellent colors are obtained in non-black vulcanizates.
It should be noted that in the application of Dimacit TMTD-PDR N-nitrosodimethylamine can be formed by the reaction of dimethylamine, a decomposition product, with nitrosating agents (nitrogen oxides).
Dimacit TMTD-PDR is regulated for use in articles in contact with food as specified under FDA 21 CFR 177.2600, 175.105 and under BgVV XXI, Categories 1-4 and “Sonderkategorie".
