rubber antioxidants and their transformation products,recently, it was reported that the rubber antioxidant n-(1,3-dimethylbutyl)N'-phenyl-p-phenylenediamine (6ppd or antioxidant 4020), a typical tire rubber antioxidant, could enter the surrounding environment together with tire-wear particles (twps).
we first give a brief introduction of the oxidation process and oxidation mechanism for rubbers. then, we present the strategies to improve the anti-oxidative efficiency of rubber antioxidants. after that, recent advances to minimize the blooming and migration of antioxidants are summarized.
rubber antioxidants and chemical 6ppd
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
rubber antioxidant 4020（6ppd） with high quality,6ppd is a polluting antioxidant. in addition to having good anti oxygen effect, it also has the functions of anti ozone, anti bending and cracking, and inhibiting harmful metals such as copper and manganese.

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.
the use of crude carbon dots as novel antioxidants for sale
overall, current purification practices severely limit the broad applications of cds materials. herein, we attempt to directly use the diethylenetriamine-passivated crude carbon dots (ccds), without energy- and time-intensive purification process, as novel antioxidants for natural rubber.
chemical rubber antioxidant 4020 (antioxidant) by lanxess: technical datasheet,chemical rubber antioxidant 4020 by lanxess is an anti-oxidant used for white-, colored- and transparent goods from solid rubber and latex. it also functions as anti-degradants and secure the vulcanizates against damaging external influences.
synthesis and properties of a novel reactive and low
rubber composites containing antioxidants 4020 and 4010na were immersed and extracted, resulting in solutions that were noticeably darker in color than those of the rubber composites with gma-ppda antioxidants, which had also been immersed.
rubber antioxidant 6ppd (4020) (high-class) with best quality,it offers antioxidant properties with excellent high temperature and flexing resistance to rubber compounds. rubber antioxidant 6ppd(4020) (high-class) is suitable for applications including solid tires, conveyors, hoses, cables, bushings, automotive mounts and general rubber 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.
- What are the different types of antioxidants in rubber?
- Chemical antioxidants are generally classified as amine, phenolic, heterocyclic, phosphite, and nickel salts (nickel dibutyl dithiocarbamate (NBC)) antioxidants according to their chemical structure (Figure 1). During the rubber production, various antioxidants are often used as a mixture to improve performance and ensure an antiaging effect.
- Does antioxidant 2246 protect rubber from aging?
- Among them, antioxidant 2246 has a good performance to protect rubber from aging caused by heat, oxygen, and metals. Because hydrogen in phenolic antioxidants can combine with the oxygen in air, their antiaging efficiency is therefore lowered compared with amine antioxidants [21, 22].
- 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) .
