- Abstract:
The article focuses on the study regarding the replacement of diorthotolyl guanidine (DOTG) as an accelerator for making Vamac ethylene acrylic elastomers (AEM polymers). It notes that the cure rate of diazobicyclo undecene (DBU), with the tradename of Vulcofac ACT 55, is closed with that of DOTG making it a good replacement as an accelerator. It says that the substitution will increase the material's compression set but can be resolved by using less volatile plasticizer.
