Zn/Al‐NO3 Layered Double Hydroxide as Alternative Activator for Nitrile Rubber Vulcanization: Effect of the Accelerator‐to‐Sulfur Ratio on Curing Kinetics and Network Properties

Journal of Applied Polymer Science, EarlyView.
Zn/Al‐NO3 layered double hydroxide offers a low‐zinc alternative for sulfur vulcanization of nitrile rubber, reducing nominal zinc loading by an estimated 71%. Its potential as a vulcanization activator depends on the curing system: conventional curing preserves tensile strength despite slower kinetics, whereas efficient curing maintains comparable ...
