  • How many rubber antioxidants are produced in China?
  • China is one of the main countries producing rubber antioxidants, and the production accounts for more than 70% of the total amount globally. The production of rubber antioxidants in China ranged from 365,000 to 378,000 tons during 2016–2020, showing a constant annual trend .
  • 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.
  • Can antioxidant 2246 be grafted to SIO 2?
  • Zhong et al. proposed a novel solid-phase method to graft the antioxidant 2246 on the surface of SiO 2 with the aid of a silane coupling agent . The as-prepared SiO 2 -s-2246 performed better than pristine antioxidant 2246 in protecting rubber from thermo-oxidative aging because of the elimination of the “blooming” defects.
  • 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.
