  • Which antioxidants are used in rubber vulcanization?
  • The amine and phenolic antioxidants are the most widely used rubber antioxidants (Fig. 1 b and c). Generally, the phenolic antioxidants have poor antioxidative efficiency (compared to amine antioxidants) and they can delay vulcanization, but they cause little discoloration problems.
  • Can rubber antioxidants contain rare-earth ions?
  • The recently reported rubber antioxidants containing rare-earth ions are summarized in Fig. 4, for instance, Sun et al. prepared a novel hindered phenol rare-earth complex (DTSm) (Fig. 4 f) by a simple and green method using 3,5-di-tert-butyl-4-hydroxybenzoic acid (DT) and samarium chloride hexahydrate (SmCl 3 ·6H 2 O) via coordination reaction.
  • Is carbon black a good reinforcing filler for rubber?
  • Nonetheless, it is difficult to immobilize the antioxidants on the surface of carbon black, which historically and presently dominates the markets of reinforcing filler for rubber because of the lost cost and excellent reinforcing effect. 4.3. Controlled release of antioxidants from hollow filler
  • Are Nr Composites a good anti-aging material?
  • The NR composites with AOs showed a higher tensile strength than the neat NR composites before aging (p < 0.05). There was no signi cant change in the tensile strength of comparable to the neat NR a er aging (p > 0.05). In contrast, the a good short-term thermo-oxidative anti-aging e ect. The
