the effect of antioxidant concentration of n-isopropyl-n,study the influence of high concentrations of antioxidants n-isopropyl-n-phenyl-p-phenylenediamine (ippd) and 2,2,4-trimethyl-1,2-dihydroquinoline (tmq) and the mixing time of the vulcanization physical properties, thermal properties, mechanical properties and structure micro on natural rubber compound has been done.
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 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 [31].
notch publishes world markets for rubber antioxidants report,notch consulting is proud to announced the publication of a new report, world markets for rubber antioxidants. the report covers current conditions and a growth forecast for rubber antioxidants, including 6ppd/ippd, tmq, phenolics, and specialties.
comparative analysis of rubber antioxidant ippd and other
explore the comparative analysis of rubber antioxidant ippd (n-isopropyl-n'-phenyl-p-phenylenediamine) with other antioxidants in this comprehensive review. learn about the anti-aging advantages, diverse application fields, and cost-effectiveness of ippd in the rubber manufacturing industry.
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.
application of rubber antioxidant ippd in oil fields
discover how rubber antioxidant ippd enhances the durability and efficiency of equipment in the challenging environments of oil fields and industrial wastewater treatment in the middle east. learn about ippd’s ability to reduce aging and corrosion, extend the life of equipment, and lower maintenance costs, ensuring long-term stable operation
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.

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.
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.
- 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.
- 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.
- 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.
- 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.
