- 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.
- How can Antioxidants improve the antioxidative capacity of the rubber matrix?
- Generally speaking, as shown in Figs. 2 and 3, there are two main strategies to improve the antioxidant's antioxidative capability for the rubber matrix: (i) using two or more antioxidants together, and (ii) molecular design of antioxidants. Fig. 2.
- Which antioxidants are used in rubber vulcanization?
- The amine and phenolic antioxidants are the most widely used rubber antioxidants (Fig. 1b 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.
- Are rubber antioxidants harmful?
- As shown in Table 1, many commonly used rubber antioxidants are damaging to human health and the environment. For example, the antioxidant MB (2-mercaptobenzimidazole), which is widely used in the manufacture of light-colored rubber products, is harmful to aquatic organisms and has a continuous effect.
- Does a sustained release of EAB improve anti-oxidative capacity of rubber composites?
- Moreover, the retention of EAB for SBR/Loaded HNTs is about 50% higher than for SBR/HNTs and CDs after the thermo-aging testing, demonstrating the sustained release of CDs from HNTs could enhance the anti-oxidative capacity of the rubber composites.
- What is the antioxidative effect of silica-s-TP for rubber composite?
- The antioxidative effect of silica-s-TP for rubber composite is superior to for the traditional antioxidants such as 4020, RD, 2246 and 264, and the high efficiency free radical capturing activity of silica-s-TP was stem from the polyphenol on the silica surface.
