PROPERTIES:
NURCHEM ZDTP-50 is a special accelerator for EPDM containing sulfur, ZnO, thiazoles and thiurams accelerators, It can lead to high degree of cross-linking and no appearance of blooming when dosage is up to maximum recommended amount. NURCHEM ZDTP-50 mastermatch has processing safety and storage stability. As an ingredient of effective vulcanization system it is an accelerator for vulcanization of rubber such as NR, IR, BR, NBR, IIR, etc and its vulcanizate has excellent heat resistance. It is a secondary accelerator with sulfenamides thiazoles, and thiurams for vulcanization of EPDM AND NR. No formation of hazardous nitrosamines takes place during vulcanization.

Compared to a traditional ZDTP liquids, NURCHEM ZDTP-50 allows :
Avoidance of smelly pungent odor of NURCHEM ZDTP-50 liquids due to masterbatch with slight odor, production environment improver.
Effective guarantee of activity of NURCHEM ZDTP-50 due to pre-dispersed masterbatch
Tack free products at room temperature, convenience and accuracy on ingredients.
Lower Mooney viscosity at lower temperature (50°C), higher quality of dispersion.
Impurity free, blocked filter free of extrusive products, scrap rate reduction and higher productivity thanks to filtration.
Wider compatibility with other elastomers.
