Actmix® ZBEC-70GE F140

Actmix® ZBEC-70GE F140 by Ningbo Actmix Rubber Chemicals is a zinc diethyl dithiocarbamate (75%). Acts as an accelerator. It contains 25wt% 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 improve processing safety. Compared to ZDBC, ZDEC has longer scorching time and shorter total vulcanization time. Alkaline accelerators can activate ZDBC. A little of ZDBC can be secondary accelerators for thiols or thiurams. Combined with antioxidant, it can improve heat resistance for NR and IR. It is compatible with 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 1.5-2.5phr.
