  • What are the future trends of rubber antioxidants?
  • The perspectives on the future trends of rubber antioxidants have been presented. Elastomers, especially diene-rubbers containing unsaturated double carbon bonds in the main chains, are vulnerable to thermal/oxygen aging, which would make the elastomers less elastic and result in earlier failure of the elastomer products.
  • Are rubber antioxidants a rational design?
  • The development of medical antioxidants also inspires the rational design of rubber antioxidants. Recently, Sun, et al. synthesized a novel antioxidant (APPT) containing aromatic amine, thiourea and allyl groups by the reaction between N-phenyl-p-phenylenediamine and allyl isothiocyanate (Fig. 3 b) .
  • How can Antioxidants improve the antioxidative capacity of the rubber matrix?
  • Generally speaking, as shown in Figs. 2 and 3, there are two main strategies to improve the antioxidant's antioxidative capability for the rubber matrix: (i) using two or more antioxidants together, and (ii) molecular design of antioxidants. Fig. 2.
  • Are rubber antioxidants harmful?
  • As shown in Table 1, many commonly used rubber antioxidants are damaging to human health and the environment. For example, the antioxidant MB (2-mercaptobenzimidazole), which is widely used in the manufacture of light-colored rubber products, is harmful to aquatic organisms and has a continuous effect.
  • How does rubber antioxidant work?
  • To prolong the service life of rubber composites by retarding their aging processes, rubber antioxidant initially relies on the use of a coating, such as paraffin, and coal tar, to physically isolate oxygen, but this protective layer would quickly lose the utility due to wear.
  • Do rubber antioxidants cause DNA damage?
  • For example, 2,6-di-tert-butyl-p-benzoquinone (BHT-Q) can cause DNA damage at low concentrations. It is obvious that the hazard of rubber antioxidants should not be underestimated. It is highly desired to comprehensively evaluate the risks associated with the antioxidants' use in products that involve environmental releases.
