Use Characteristics: Konson® ZDTP-50 is used as a special accelerator for EPDM compounds containing accelerators of the thiazol and thiuram class as well as sulphur and zinc oxide. Konson® ZDTP-50causes a high degree of cross-linking. Vulcanizates accelerated by Konson® ZDTP-50 show no signs of blooming when observing the recommendation for the maximium dosage. With the use of Konson® ZDTP-50 accelerator systems can be obtained that exhibit a very good processing safety and storage stability of the accelerated raw compounds. As an ingredient of EV systems Konson® ZDTP-50 can be used to accelerate the vulcanzation of NR, IR, SBR, NBR, IIR etc. The vulcanizates are then characterized by exceptionally good resistance to heat. Konson® ZDTP-50 is used as a secondary accelerator in the sulphur vulcanization of EPDM and NR in combination with sulphen amides, thiazoles and thiurams. It does not build secondary amines during the vulcanization process which can form hazardous N-nitrosamines.

Processing Advantages: The thermoplastic, excellent compatible EPDM/EVA binder which is combined with active dispersing promoters allows much more easily and quickly incorporation and excellent dispersion in the rubber mixing. In this way, optimal activity of the effective liquid ZDTP is assured.
