Use

Mode of action: Isogran® ZDTP/S is used as a special accelerator for EPDM compounds containing accelerators of Thiazol and Thiuram class as well as sulphur and zinc oxide. Vulcanizates accelerated by Isogran® ZDTP/S show no signs of blooming when observing the recommendation for the dosage. When using Isogran® ZDTP/S, accelerator systems can be obtained, that exhibit a very good processing safety and storage stability of the accelerated compounds.

As an ingredient of EV systems Isogran® ZDTP/S can be used to accelerate the vulcanization of NR, IR, SBR, NBR, IIR etc. The vulcanizates are then characterized by good resistance to heat ageing.

Isogran® ZDTP/S is used as a secondary accelerator in the sulphur vulcanization of EPDM and NR in combination with Sulphenamides, Thiazoles and Thiurams. It does not build secondary amines during the vulcanization process. Therefore it doesn’t form hazardous N-Nitrosamines.

Processing: Isogran® ZDTP/S allows quick absorption and good dispersion in the rubber.

Dosage

Usual dosage of Isogran® ZDTP/S: 2 – 4 phr

Recommended combination with Isogran® MBT-80: 0.6 – 1.9 phr

Recommended combination with Isogran® TMTD-80: 0.3 – 1 phr

In compounds filled with very large amounts of fillers (carbon black, mineral filler or processing oils) the optimal dosage of Isogran® ZDTP/S is: 5 phr
