In this research, we reported a novel and simple approach to using tetramethylthiuram disulfide (TMTD) to prepare self-healing vulcanized natural rubber. TMTD as a sulfur donor and accelerator was used with different contents, ranging from 1.0 to 3.0 phr, to vulcanize high ammonia natural rubber (HANR). The best self-healing performance, i.e., 50–60% stress recovery and 80–95% strain recovery, was achieved for vulcanized natural rubber samples with 1.5 to 2.0 phr loading of TMTD. This approach discovered the potential application of TMTD in preparing self-healing vulcanized natural rubber.
