environmental profiles, hazard identification for sale,n-(1,3-dimethylbutyl)-n'-phenyl-p-phenylenediamine (6ppd) is commonly used in rubber compounds as antioxidants to protect against degradation from heat, oxygen, and ozone exposure. this practice extends the lifespan of rubber products, including tires, by preventing cracking, aging, and deterioration.
this makes antioxidants the most consumed type of rubber additive around the globe, with ppds (representative products: 6ppd) making up 56–60% of the total. the organization for economic co-operation and development (oecd) has classified 6ppd, the most widely used tire antioxidant among ppds, as a high production volume (hpv) chemical ( oecd
transformation products of tire rubber antioxidant 6ppd for sale
6ppd, a tire rubber antioxidant, poses substantial ecological risks because it can form a highly toxic quinone transformation product (tp), 6ppd-quinone (6ppd), 6PPD is compatible with a wide range of rubber types, including natural rubber and various synthetic rubbers, making it versatile for different formulations.
6ppd rubber antioxidant: characteristics, applications,6ppd (n-(1,3-dimethylbutyl)-n'-phenyl-p-phenylenediamine) is a highly effective rubber antioxidant with notable characteristics, including excellent heat resistance, anti-flex cracking properties, and compatibility with various rubber types.
rubber antioxidants and their transformation products
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 antioxidants and their tps.
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.
new evidence of rubber-derived quinones in water, air for sale
our results demonstrated that five rubber-derived quinones, including 6ppd-quinone, existed in the environment as the transformation products of ppd antioxidants. such findings greatly expand the existing knowledge of ppd-derived quinones and thus may provide opening clues and promote further investigations on their environmental fate and
widely used chemical rubber antioxidant ippd,N-Isopropyl-N'-phenyl-p-phenylenediamine (often abbreviated ippd) is an organic compound commonly used as an antiozonant in rubbers. like other p-phenylenediamine-based antiozonants it works by virtue of its low ionization energy, which allows it to react with ozone faster than ozone will react with rubber. [2]
widely used good price rubber antioxidant ippd
substituted para-phenylenediamine (ppd) antioxidants have been extensively used to retard oxidative degradation of tire rubber and were found to pervade multiple environmental compartments. however, there is a paucity of research on the environmental occurrences of their transformation products.
p-phenylenediamines (ppds) and ppd-quinones- sciencedirect,with the increasing demand for private automobiles and tire production, tire wear particles have emerged as a significant source of microplastics [1].to enhance the service life of automotive tires and mitigate cracking and thermo-oxidative degradation, p-phenylenediamines (ppds), such as n-1,3-dimethylbutylN'-phenyl-p-phenylenediamine (6ppd), have been widely incorporated as antioxidants
- 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.
- Does 6PPD ozonation pose environmental risks?
- 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.
- 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.
- 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.
