6ppd (cas 793-24-8) high quality rubber antioxidant,6ppd is a substituted p-phenylenediamine. 1 it scavenges ozone, forming nitroxyl radicals. 2 6ppd decreases hatchability of zebrafish embryos by 25.6 and 78.9% when used at concentrations of 0.022 and 0.22 mg/l, respectively. 1 it also reduces motility and body length, as well as induces developmental malformations and oxidative stress in, zebrafish embryos.
recent progress in the rubber antioxidants price
the commonly used rubber antioxidant can be divided into primary antioxidant and secondary antioxidant according to the anti-aging mechanism [13]. the primary antioxidants, such as aryl amines and phenolic antioxidants, could inhibit the propagation reaction by supplying the reactive hydrogen atom to the free radicals.

- 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.
- 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.
