transformation products of tire rubber antioxidant 6ppd for sale,6ppd reactions with ozone generate numerous ubiquitous and potentially bioactive transformation products that can be detected in tire rubber particles and roadway environments.
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.
p-phenylenediamines and p-phenylenediamine quinone
we quantified ppds and ppd quinone derivatives (ppd-qs) in rubber consumer products, including car tires, rubber belts, rubber gloves, rubber cables, and rubber antioxidant tmq, to obtain information on the degree of weathering over time during their use.
improvements of lanthanum complex on the thermal-oxidative,mixed antioxidants composed of antioxidant ippd and novel rare earth lanthanum complex were used as an additive to prepare natural rubber (nr) samples. the variations of macro-properties, surface characterizations, and internal groups were investigated by mechanical testing, x-ray photoelectron spectroscopy, and thermogravimetric analysis
environmental fate of tire-rubber related pollutants 6ppd
To improve tire durability, the antioxidant n-(1,3-dimethylbutyl)-n-phenyl-p-phenylenediamine (6PPD) is used in rubber, but when exposed to oxidants such as ozone (O3), it is converted into toxic 6PPD quinone (6PPD-Q), causing ecological problems.
first grade quality 6ppd rubber antioxidant,recently, roadway releases of n,n′-substituted p-phenylenediamine (ppd) antioxidants and their transformation products (tps) received significant attention due to the highly toxic 6ppd-quinone. however, the occurrence of ppds and tps in recycled tire rubber products remains uncharacterized.
rubber antioxidants: tmq, 6ppd, ippd chemical products
rubber antioxidant IPPD, or n-isopropyl-n'-phenyl-p-phenylenediamine, is a synthetic rubber antioxidant widely used in the tire and rubber industry. It prevents degradation caused by heat, oxygen, and flex cracking.
rubber antioxidants and chemical 6ppd,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.
enhancing rubber performance with antioxidant ippd
this article will introduce the excellent antioxidant properties of rubber antioxidant ippd and its important role in improving the performance of rubber products, providing valuable information and insights for relevant practitioners in the industry.

- Are p phenylenediamine (PPD) antioxidants in recycled tire rubber products toxic?
- Recently, roadway releases of N, N ′-substituted p -phenylenediamine (PPD) antioxidants and their transformation products (TPs) received significant attention due to the highly toxic 6PPD-quinone. However, the occurrence of PPDs and TPs in recycled tire rubber products remains uncharacterized.
- What are rubber antioxidants?
- Rubber antioxidants are defined as substances that could delay the aging of polymer compounds and prolong the service life of rubber products by inhibiting oxidation, heat, or light radiation . To date, the annual global consumption of rubber antioxidants is over 700,000 tons, accounting for about 40% of the total amount of rubber additives.
- How does a rubber matrix affect antioxidative performance?
- Obviously, the solubility/dispersity of the antioxidant within the rubber matrix is a key factor in determining the antioxidative performance, and the antioxidative efficiency of antioxidant increases with the dispersion state within the rubber matrix, owing to higher specific surface area available for termination of radicals.
- Which rubber antioxidants are used in China?
- Amine antioxidants are the main rubber antioxidants produced and used in China, of which 6PPD and 2,2,4-Trimethyl-1,2-dihydroquinoline (TMQ, RD) have the highest production, accounting for more than 80% of the total amine antioxidants.
