Perkacit TETD is used as a primary or secondary (ultra) accelerator in multiple blend accelerator systems with thiazoles and sulfenamides. It is also used as a vulcanizing agent (sulfur donor) in most of the sulfur cured elastomers and as a peptizing agent in sulfur modified polychloroprenes.
- Perkacit TETD offers fast vulcanization and gives more scorch delay than Perkacit TMTD.
- It gives an excellent vulcanization plateau with good heat aging and compression set resistance when used in sulfurless vulcanization systems and EV systems.
- In EPDM, Perkacit TETD is a valuable secondary accelerator.
- Perkacit TETD gives excellent dispersions in soft compounds due to its low melting point.
- Perkacit TETD is non-staining and non-discoloring
excellent colors are obtained in non-black
vulcanizates.
- It should be noted that in the application of Perkacit TETD N-nitrosodiethylamine can be formed by the reaction of diethylamine, a decomposition product, with nitrosating agent (nitrogen oxides).
- Perkacit TETD 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. |
