rubber antioxidants and their transformation products mdpi,antioxidants are prevalently used during rubber production to improve rubber performance, delay aging, and extend service life. however, recent studies have revealed that their transformation products (tps) could adversely affect environmental organisms and even lead to environmental events, which led to great public concern about environmental occurrence and potential impacts of rubber.
rubber antioxidants: tmq, 6ppd, ippd price
antioxidant 6ppd (4020) 6ppd, or n-1,3-dimethylbutyl-n’-phenyl-p-phenylenediamine, is a synthetic rubber antioxidant widely used in the tire and rubber industry. it provides protection against degradation caused by heat, oxygen, and flex-cracking. 6ppd acts as a stabilizer and antiozonant, preventing the formation of harmful free radicals and.

- 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.
- 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.
- 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. 4 f) by a simple and green method using 3,5-di-tert-butyl-4-hydroxybenzoic acid (DT) and samarium chloride hexahydrate (SmCl 3 ·6H 2 O) via coordination reaction.
- Are rubber antioxidants a rational design?
- The development of medical antioxidants also inspires the rational design of rubber antioxidants. Recently, Sun, et al. synthesized a novel antioxidant (APPT) containing aromatic amine, thiourea and allyl groups by the reaction between N-phenyl-p-phenylenediamine and allyl isothiocyanate (Fig. 3 b) .
