Product description: Detailed Product Description Manufacturer,export experienced,large stable capacity, high quality,continuable,environmental,ISO9001/14001,REACH pre-register, HiDispersion Predispersed Rubber Chemicals ZDBC-80 Super accelerator for the curing of natural and diene synthetic rubbers Product description Composition 80% zinc-dibutyl-dithiocarbamate, 20% EPDM/EVA binder and dispersing agents Appearance White to yellowwish granules Density,20 oC Approx. ~ 1.16 g / cm3 (20oC) Physiological properties : See safety data sheet (MSDS) Raw material characteristics of ZDBC: Melting point ~ 104 oC Evaporation loss ≤ 0.5% ZDBC content ≥ 97% Sieve residue 63µm ≤ 0.5 % Zinc Content 13.0 - 15.0 % Ash content ≤ 0.5 % Use Characteristics HiDispersion ZDBC-80 causes very rapid vulcanization of natural and synthetic rubbers, e.g. SBR, NBR and EPDM. The addition of thiuram and thiazole accelerators can retard the curing rate increase processing safety. HiDispersion ZDBC-80 has a shorter scorch time and a slower total curing time than ZDEC-80, ZEPC-80 and ZDMC-80. Baisc accelerators have an activating effect on HiDispersion ZDBC-80. HiDispersion ZDBC-80 is also used in small amounts for secondary acceleration and activation of compounds which are going to be cured with mercapto or thiuram accelerators. HiDispersion ZDBC-80 gives the vulcanizates very good tensile and resilience properties. It is recommended to add antioxidants to improve resistance to ageing especially of NR and IR. 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 ZDBC is assured. Dosage levels NR: 0.6 - 1.0 phr; as secondary accelerator: 0.1 - 0.2 phr; SBR and NBR: 0.6 - 1.2 phr; as secondary accelerator: 0.1 - 0.2 phr. Applications Suitable for technical rubber articles based on NR, EPDM, IR, SBR, NBR or IIR. Packaging Net 25 kg cartons with plastic inner. Storage stability In original closed containers under cool and dry conditions max. 2 years. Handling Consult material safety data sheet (MSDS) for additional handling information.
