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.
environmental fate of tire-rubber related pollutants 6ppd
the continuous release of ppds in the environment triggers chemical reactions, resulting in the formation of other emerging pollutants and subsequent environmental contamination (zhang et al., 2024a). 6ppd is the most extensively used rubber antioxidant, reaching a production volume of 200 thousand tons in china in 2020 (zhang et al., 2022).

6ppd chemical active antioxidant,6ppd is a common rubber antiozonant found in vehicle tires. it is mobile within the rubber and slowly migrates to the surface via blooming. on the surface it forms a "scavenger-protective film" that reacts with the ozone more quickly than the ozone can react with the rubber. this process forms aminoxyl radicals and was first thought.
- Is 6PPD a toxic oxidant?
- To enhance tire durability, the antioxidant N- (1,3-dimethylbutyl)-N′-phenyl-p-phenylenediamine (6PPD) is used in rubber, but it converts into the toxic 6PPD quinone (6PPD-Q) when exposed to oxidants like ozone (O 3), causing ecological concerns.
- 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 causes oxidative aging of rubber?
- Various external factors, including oxidative agents (such as oxygen), heavy metals, UV rays, ozone, mechanical stress, heat, and aggressive chemicals, etc., could accelerate rubber aging. This review mainly focused on thermo-oxidative aging because it is the most common aging type for rubbers.
- 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.
