  • What is a tyre antioxidant used for?
  • Antioxidant - Used to prevent oxidation of the rubber when the tyre reaches higher temperatures as it is full of air that contains oxygen. Sulfur - Used in the process of vulcanisation. Sulfur and zinc oxide, are crucial ingredients to transform rubber into a solid article during vulcanization or tyre curing.
  • 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.
  • 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.
  • What is a synthetic rubber tyre?
  • Synthetic Rubber - Synthetic rubbers are a man-made elastomer synthesised from petroleum by using solution or emulsion polymerisation methods. The two main synthetic rubber polymers used in tyre manufacturing are butadiene rubber and styrene-butadiene rubber. These rubber polymers are used in combination with natural rubber.
  • Can rubber antioxidants contain rare-earth ions?
  • The recently reported rubber antioxidants containing rare-earth ions are summarized in Fig. 4, for instance, Sun et al. prepared a novel hindered phenol rare-earth complex (DTSm) (Fig. 4f) by a simple and green method using 3,5-di-tert-butyl-4-hydroxybenzoic acid (DT) and samarium chloride hexahydrate (SmCl3 ·6H 2 O) via coordination reaction.
  • 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.
