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.
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.

recent progress in the rubber antioxidants price,separately, 4-(dimethyl-butyl amino)diphenylamine (6ppd), another widely used antioxidant in the rubber industry, a recent study reported that the 6ppd (or already converted 6ppd-quinone) released from the tires reacts to form 6ppd-quinone, which is toxic to coho salmon and causes mass coho salmon deaths in the u.s. pacific northwest [59].
rubber antioxidants and their transformation products
the tps of rubber antioxidants have been observed in some studies under environmental conditions. as one of the widespread rubber antioxidants, amine antioxidants (ppds: tmppd, dppd, 6ppd, and 6ppdtz) could react with o 3 (in parts per billion volume levels) in the environment and produce ppd-quinone .

a nation-wide study for the occurrence of 6ppd antioxidants
road dust is the main source of rubber-derived ppds and 6ppd-q and closely related to human health. the daily intakes of 6ppds and 6ppd-q by dermal absorption and ingestion from road dust were estimated for adults and children based on the concentrations of target compounds measured in urban trunk road dust in the present study. as shown in fig. s6.
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.

transformation products of tire rubber antioxidant 6ppd in,6ppd, a tire rubber antioxidant, poses substantial ecological risks because it can form a highly toxic quinone transformation product (tp), 6ppd-quinone (6ppdq), during exposure to gas-phase ozone. important data gaps exist regarding the structures, reaction mechanisms, and environmental occurrence of tps from 6ppd ozonation. to address these data gaps, gas-phase ozonation of 6ppd was.
- 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.
- 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.
- 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.
