    Thiourea accelerators in the vulcanization of butyl

    1-phenyl-3-(N,N'-diphenylamidino) thiourea has been used as a secondary accelerator with TMTD and MBTS in the sulfur vulcanization of natural rubber (figure 13) (refs. 14 and 15). It was found that the more nucleophilic the secondary accelerator, the less the optimum cure.

    An accelerator is defined as a compound that increases the speed of vulcanization and that enables vulcanization to proceed at lower temperature and with greater efficiency. Accelerator also decreases the amount of sulfur needed to cross-link the polydiene, which improves the aging properties of the vulcanized rubber.
