- 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.
- What causes oxidative aging of rubber?
- Various external factors, including oxidative agents (such as oxygen), heavy metals, UV rays, ozone, mechanical stress, heat, and aggressive chemicals, etc., could accelerate rubber aging. This review mainly focused on thermo-oxidative aging because it is the most common aging type for rubbers.
- 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) .
- What happens if rubber ages?
- Rubbers, especially the diene-rubbers containing double bonds in their main chains, are particularly susceptible to aging, leading to the deterioration of the outlook, hardness, and physical/mechanical performances. The aging of the rubber would even lead to a great waste of rubber resources and threaten people's lives and safety.
