  • What is vulkanox 4020?
  • Vulkanox® 4020 by Lanxess is an anti-oxidant used for white-, colored- and transparent goods from solid rubber and latex. It also functions as anti-degradants and secure the vulcanizates against damaging external influences.
  • Does antioxidant 2246 protect rubber from aging?
  • Among them, antioxidant 2246 has a good performance to protect rubber from aging caused by heat, oxygen, and metals. Because hydrogen in phenolic antioxidants can combine with the oxygen in air, their antiaging efficiency is therefore lowered compared with amine antioxidants [21, 22].
  • 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.
  • 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.
