Use Characteristics: A nitrosamine free super accelerator Konson® ZBEC-70 is a fast action thiocarbamate accelerator which has not been found to produce any harmful cancer-causing materials. Konson® ZBEC-70 can be used as a primary or secondary accelerator both in natural and synthetic rubbers, e.g. EPDM, IR, SBR, NBR, IIR. Compared with conventional dithiocarbamate accelerators, Konson® ZBEC-70 has a high level of processing safety. In compounds containing thiazole or sulphenamide accelerators, Konson® ZBEC-70 has an activating effect. Appropriate matching dosage of Zinc oxide and sulfur when using, the aliphatic acid (e.g. stearic acid) is not necessary. When same molar dosages of ZBEC-70 are used, vulcanizates containing Konson® ZBEC-70 demonstrate similar modulus to other dithiocarbamates.

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 ZBEC is assured.
