Predispersed Rubber Chemicals ZBEC-70
Category : Catalyst and Auxiliary/Rubber Auxiliary Agent
CAS NO : EC NO : MF : MW : Packing : 25 kg Product description : Detailed Product Description Manufacturer experienced,Stable , continuable,environmental ISO9001,ISO14001,REACH pre-register.Powder,Granular,Masterbatch HiDispersion Predispersed Rubber Chemicals ZBEC-70 Nitrosamine free ultra accelerator for the curing of natural and synthetic rubbers Product description Composition 70% Zinc-dibenzyl- dithiocarbamate, 30% EPDM/EVA binder and dispersing agents Appearance Light-yellow granules Density,20 oC Approx. ~ 1.22 g / cm3 (20oC) Physiological properties : See safety data sheet (MSDS) Raw material characteristics of ZBEC: Melting point ~ 178 oC Evaporation loss ≤ 0.5% ZBEC content ≥ 97% Sieve residue 63µm ≤ 0.5 % Zinc Content 10.0 - 11.5 % Ash content ≤ 0.5 % Use Characteristics A nitrosamine free super accelerator HiDispersion ZBEC-70 is a fast action thiocarbamate accelerator which has not been found to produce any harmful cancer-causing materials. HiDispersion 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, HiDispersion ZBEC-70 has a high level of processing safety. In compounds containing thiazole or sulphenamide accelerators, HiDispersion 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 HiDispersion 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. Dosage levels EPDM: HiDispersion ZBEC-70: 0.8-2.5 phr HiDispersion S-80: 1.0-2.0 phr HiDispersion MBT (MBTS)-80: 1.0-2.0 phr HiDispersion CBS-80: 0.5-1.5 phr; NR, SBR, NBR: HiDispersion ZBEC-70: 0.8-2.0 phr HiDispersion S-80: 1.0-2.0 phr HiDispersion MBT (MBTS)-80: 0.5-3.0 phr.
