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
recent progress in the rubber antioxidants Rubber Auxiliary Agent
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 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.

when employed in styrene-butadiene rubber (sbr)/silica composites, appt endowed the composites with much better antioxidative properties than the commercial antioxidant n-isopropylN'-phenyl-p-phenylenediamine (ippd), oxidation induction time (oit) of composites containing appt (126.61 min) was almost twice as long as that with ippd (63.87
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.

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), during exposure to gas-phase ozone. important data gaps exist regarding the structures, reaction mechanisms, and environmental occurrence of tps from 6ppd ozonation.
rubber antioxidants and their transformation products,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.
- Do antioxidants and their TPS increase environmental risk awareness of rubber products?
- To our knowledge, this is the first review on antioxidants and their TPs in the environment, which may elevate the environmental risk awareness of rubber products and their TPs in the near future.
- 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.
- Can a rubber antioxidant enter the environment with tire-wear particles (Twps)?
- Recently, it was reported that the rubber antioxidant N - (1,3-dimethylbutyl)- N′ -phenyl- p -phenylenediamine (6PPD or antioxidant 4020), a typical tire rubber antioxidant, could enter the surrounding environment together with tire-wear particles (TWPs) [7, 8].
