Accelerator ZDMC-80 Masterbatch
Pubdate：2019/04/29 Predispersed rubber chemical Masterbatch views：180
Konson® Accelerator ZDMC-80 Masterbatch
Composition 80% Zinc-dimethyl- dithiocarbamate,
20% EPDM/EVA binder and dispersing agents
Appearance White granules
Density,20 oC 1.32-1.52 g / cm3 (20oC)
Physiological properties : See safety data sheet (MSDS)
Raw material characteristics of ZDMC:
Melting point ~ 244 oC Evaporation loss ≤ 0.5%
ZDMC content ≥ 97% Sieve residue 63µm ≤ 0.5 %
Zinc Content 20.0 – 24.5% Ash content ≤ 0.5 %
Use Characteristics Konson®ZDMC-80 causes very rapid vulcanization of natural and synthetic rubbers, e.g. SBR, NBR and EPDM. The addition of thiuram and thiazole accelerators retards the start of the vulcanization and increases processing safety. Konson®ZDMC-80 gives a longer scorch time and a faster total curing time than Konson®ZDBC-80, Konson®ZDEC-80 and Konson® ZEPC-80.Konson®ZDMC-80 receives an additional activation from basic accelerators.Konson® ZDMC-80 is also used in small amounts for secondary acceleration and for the activation of mixes, which are going to be cured with mercapto or thiuram accelerators. Konson®ZDMC-80 provides very good tensile and resilience properties. For improving the resistance to aging, it is recommended to add antioxidants
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 ZDMC is assured.
Dosage levels NR: 0.3 – 0.8 phr; as secondary accelerator: 0.05 – 0.3 phr;
SBR and NBR: 0.8 – 1.2 phr; as secondary accelerator: 0.05 – 0.3 phr.
Applications Suitable for technical rubber articles based on NR, EPDM, IR, SBR, NBR or IIR. Specially for light-colored articles and transparent articles.
