  • Does TMTD vulcanize high ammonia natural rubber (hanr)?
  • 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.
  • What vulcanizing agent is used in rubber?
  • Elemental sulfur is the predominant vulcanizing agent for general-purpose rubbers. It is used in combination with one or more accelerators and an activator system comprising zinc oxide and a fatty acid (normally stearic acid). The most popular accelerators are delayed-action sulfenamides, thiazoles, thiuram sulfides, dithocarbamates and guanidines.
  • What is the optimum TMTD content for rubber vulcanization?
  • The optimum TMTD content for rubber vulcanization was from 1.5 to 2.0 phr, and the temperature to achieve the best self-healing performance was 150 °C, during which the tensile strength obtained was approximately 4–6 MPa, with 50–60% stress recovery and 80–95% strain recovery.
  • How does a thiuram disulfide vulcanize?
  • Part or all of the sulfur may be replaced by an accelerator that is also a sulfur donor such as a thiuram disulfide. The accelerator determines the rate of vulcanization, whereas the accelerator to sulfur ratio dictates the efficiency of vulcanization and, in turn, the thermal stability of the resulting vulcanizate.
