  • 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.
  • Does antioxidant 4010na increase k value in Nr/CB/Nr composite?
  • Moreover, upon adding antioxidant 4010NA into NR or CB/NR composite, the K values for 4010NA/NR or 4010NA/CB/NR composite did not exhibit a significant improvement. In contrast, it is noticeable that the addition of 4010NA caused a significant increase in K value for 4010NA/SiO 2 /NR composites in comparison with SiO 2 /NR composite.
  • Does antioxidant 4010na play a better protective role in 4010na/sio 2 /nR composite?
  • Of note, antioxidant 4010NA played a better protective role in 4010NA/SiO 2 /NR composite depending on the difference in the carbonyl increase rate for the presence and absence of antioxidant 4010NA, i.e., NR and 4010NA/NR, CB/NR and 4010NA/CB/NR, SiO 2 /NR and 4010NA/SiO 2 /NR.
  • What are the commercial products of heterocyclic antioxidants?
  • The commercial products of heterocyclic antioxidants mainly include 2-mercaptobenzimidazole (MB), 2-mercaptomethylbenzimidazole (MMB), 2-mercaptobenzimidazole zinc salt (MBZ), 2-mercaptomethylbenzimidazole zinc salt (MMBZ) and the benzothiazole derivatives . Among them, MB and MBZ are the two most common products.
