Self-healing performance of vulcanized natural rubber using MgO/ZnO as a binary activator

Self-healing vulcanized natural rubber (V-NR) was prepared with MgO/ZnO as a binary activator system in the study. Standard Vietnam Rubber Grade 3L (SVR3L) was used as NR source. The SVR3L was vulcanized with ZnO, MgO/ZnO, or MgO as activators and other vulcanizing reagents.
