Actmix® ZDMC-75GE F140

Actmix® ZDMC-75GE F140 by Ningbo Actmix Rubber Chemicals is a zinc dimethyl dithiocarbamate (75%). Acts as an accelerator. It contains 25 wt% polymer binder and dispersing agent. It can improve tensile strength and resilience of its vulcanizate. Addition of thiurams and thiazoles can delay initial vulcanization and improves processing safety. Compared to ZDBC, ZDEC and ZDPC, ZDMC has longer scorching time and shorter total vulcanization time. Alkaline accelerators can activate ZDMC. A little of ZDMC can be secondary accelerators for thiols or thiurams. Combined with antioxidant, Actmix® ZDMC-75GE F140 can improve heat resistance for NR and IR. Used in natural and synthetic rubber such as SBR, NBR and EPDM. Its recommended addition level for NR is 0.6-1.0phr, as a secondary accelerator is 0.1-0.2phr, for SBR/NBR is 0.6-1.2phr, as a secondary accelerator is 0.1-0.2phr and for EPDM is 1.5-2.5 phr.
