ippd antioxidants: enhance product stability and longevity,discover how ippd antioxidants can significantly improve product stability and extend service life. explore their applications in plastics and rubber, and learn how they enhance market competitiveness.
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.

recent progress in the rubber antioxidants Rubber Auxiliary Agent
therefore, for a real application, the antioxidants are indispensable to retard the thermal-oxidative-aging process of the rubber composites and then prolong the service life. in this review, we systematically review the recent progress of antioxidants for rubber.
the effect of antioxidant concentration of n-isopropyl-n,the purpose of this study is to compare the effect of anti-oxidants types ippd and tmq and mixing time of vulcanization of the physical properties, mechanical properties, microstructure and elemental composition of the synthesis of natural rubber compound.
rubber antioxidant 4010 (ippd) with best price
Rubber antioxidant 4010 (ippd) chemical name: n-isopropyl-n'-phenyl-p-phenylenediamine. Molecular formula: c15h18n2. It is commonly used in tire manufacturing and can significantly improve the aging resistance and overall performance of rubber, helping to improve durability and safety.
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.

mixed antioxidants composed of antioxidant ippd and novel rare earth lanthanum complex were used as an additive to prep. natural rubber (nr) samples. the variations of macro-properties, surface characterizations, and internal groups were investigated by mech. testing, xps, and thermogravimetric anal. coupled with fourier transform ir
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.
influence of different types of antioxidants on the aging
influence of period of thermo-oxidative aging at 80 ℃ on the storage modulus g′ as a function of amplitude for nr vulcanizates with 60 phr carbon black and by using of different kinds of antioxidants: ippd (a), 6ppd (b) and tmq (c).
rubber antioxidants and chemical 6ppd,natural antioxidants are only found in nr, such as amino acids, tocotrienol, and betaines , whereas physical and chemical antioxidants are widely used in various synthetic rubber products.
- Do substituted para phenylenediamine (PPD) antioxidants affect the environment?
- 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.
- How many rubber antioxidants are produced in China?
- China is one of the main countries producing rubber antioxidants, and the production accounts for more than 70% of the total amount globally. The production of rubber antioxidants in China ranged from 365,000 to 378,000 tons during 2016–2020, showing a constant annual trend .
- 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.
- Does antioxidant 2246 protect rubber from aging?
- Among them, antioxidant 2246 has a good performance to protect rubber from aging caused by heat, oxygen, and metals. Because hydrogen in phenolic antioxidants can combine with the oxygen in air, their antiaging efficiency is therefore lowered compared with amine antioxidants [21, 22].
