  • How does a rubber matrix affect antioxidative performance?
  • Obviously, the solubility/dispersity of the antioxidant within the rubber matrix is a key factor in determining the antioxidative performance, and the antioxidative efficiency of antioxidant increases with the dispersion state within the rubber matrix, owing to higher specific surface area available for termination of radicals.
  • Is MBZ 445 a good antioxidant for EPDM?
  • In the thermal-aging testing, the retention of elongation at break for the rubber sample with combined antioxidants (MBZ:445=2:1) is superior to that of other samples (Fig. 2 c), demonstrating the synergistic antioxidative effects between MBZ and 445 for EPDM.
  • 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
  • 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.
