rubber antioxidants and their transformation products,in this review, we first summarize the category and application of rubber antioxidants in the world, and then demonstrate the formation mechanism of their tps in the environment, emphasizing their influence on the ozone oxidative degradation.
Detailed introduction. Rubber antioxidant 4020/6PPD. Chemical name: N-(1,3-dimethylbutyl)-N'-phenyl-p-phenylenediamine. Molecular formula: C18H24N2. CAS number: 793-24-8. Molecular weight: 268.40. 6PPD is a phenylenediamine rubber antioxidant with good compatibility with rubber, not easy to bloom, low volatility and low toxicity.
6-ppd antioxidant 4020 antioxidant rubber additive
6-ppd (antioxidant 4020) is an antioxidant that is the most commonly used additive in rubber and enters the environment through large emissions of tire wear particles. 6-ppd can induce neurodegeneration in caenorhabditis elegans.
rubber antioxidant 4020 6ppd for Tyres,applications include the use in pneumatic tire components, solid tires, belts, hoses, cable, automotive mounts, bushing and general mechanical products that are exposed to continuous and intermittent dynamic operating conditions and require protection from ozonation.

we use advanced mechanical, cryogenic and ambient technologies to produce crumb rubber from whole scrap tires to custom sizes ranging from 8 mesh (2.36 mm) to finely ground crumb rubber of 90 mesh (0.178 mm).
recent progress in the rubber antioxidants Rubber Auxiliary Agent,therefore, for a real application, the antioxidants are indispensable to retard the thermal-oxidative-aging process of the rubber composites and then prolong the service life. in this review, we systematically review the recent progress of antioxidants for rubber.
- Which antioxidants are used in rubber vulcanization?
- The amine and phenolic antioxidants are the most widely used rubber antioxidants (Fig. 1 b 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 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) .
- 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.
- Why do we need antioxidants for rubber composites?
- Therefore, for a real application, the antioxidants are indispensable to retard the thermal-oxidative-aging process of the rubber composites and then prolong the service life. In this review, we systematically review the recent progress of antioxidants for rubber.
