Product Description ZDMC(PZ)-80 is a polymeric dispersion of zinc dimethyl dithiocarbamate. This masterbatch dispersion has fast curing rate in NR, SBR, NBR and EPDM. It can delay the start of curing with thiuram and thiazole, and increase processing safety. Compared with pre-dispersed accelerator ZDBC(BZ)-80, ZDEC(ZDC EZ)-80 and ZEPC(PX)-80, it has long scorch time and fast curing rate. Alkaline accelerator gives active effect to ZDMC(PZ)-80. Slight ZDMC(PZ)-80 is used as assistant accelerator for thiol or thiuram. It imparts high tensile strength and resilience to vulcanizate.


Processing Characteristics Generally, ZDMC(PZ) powder has high melting point and large particle diameter, then it is so difficult to soften and disperse at processing temperature that vulcanization activity and mechanical properties of vulcanizate lower. However, ZDMC(PZ)-80 is formed by pre-dispersing selected ZDMC(PZ) powder to binder with certain surfactant. ZDMC(PZ)-80 disperses easily in kinds of rubber compounds to keep optimal activity of ZDMC(PZ). ZDMC(PZ)-80 has good dosing property and fluidity, no irritating dust and no material loss.


Dosage NR: 0.3 ~0.8 phr;

            SBR/ NBR: 0.8 ~ 1.2 phr;

            As assistant accelerator: 0.05 ~ 0.3phr.


Applications ZDMC(PZ)-80 is used for NR, EPDM, IR, SBR, NBR and IIR, especially for light-colored and transparent rubber products.


Packaging Coextruded paper bags lined with plastic film, net weight 25Kg/bag.


Storage Store in a cool, dry, well-ventilated area away from sunlight for up to 1 year.


Safety and toxicity Refer to related MSDS.
