Rubber Antioxidant 6PPD Antioxidant 4020 CAS 793-24-8,this study comprehensively characterized the occurrence of 9 ppds in human urine from 151 chinese adults. our results showed that all target ppds were detected in human urine samples, with the total concentrations of ppds ranging from 0.41 to 38 ng/ml.
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.

furthermore, based on the tga/ft-ir results and quantum mechanics simulations, the autocatalytic, free radical chain reaction mechanism for the thermal-oxidative aging of nr was clarified, and the different function mechanisms of antioxidants ippd and p-asala were also discussed.
recent progress in the rubber antioxidants Rubber Auxiliary Agent,in the thermal-aging testing, the retention of elongation at break for the rubber sample with combined antioxidants (mbz:445=2:1) is superior to that of other samples (fig. 2 c), demonstrating the synergistic antioxidative effects between mbz and 445 for epdm.

results. the highest antioxidant activity in terms of dpph radical scavenging was found in verbascum sinuatum l. var (vs) with an ic50 equal to 263.52 ± 5.981 μg/ml and rosa damascena mill (rd) with and ic50 equal to 287.9 ± 5.675 μg/ml that are higher than gallic acid (ic50 = 25.32 ± 5.593 μg/ml).
chemical antioxidant ippd for Tyre and Rubber Industry,antioxidant properties with excellent high temperature, fatigue and flex resistance to rubber compounds. while used primarily for ozone resistance, it is a more active antioxidant than quinoline or diphenylamine based antioxidants.
on the dehydrogenation of n,n′-substituted p-phenylenediamine
using b3lyp/6-31g ∗ treatment, the optimal geometries, electronic structures and ir spectra of n -phenyl- n ′-isopropyl- p -phenylenediamine antioxidant (ippd) and its doubly dehydrogenated oxidation products have been obtained.
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 and chemical 6ppd,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.
- 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.
- Is MBZ 445 a good antioxidant for EPDM?
- In the thermal-aging testing, the retention of elongation at break for the rubber sample with combined antioxidants (MBZ:445=2:1) is superior to that of other samples (Fig. 2 c), demonstrating the synergistic antioxidative effects between MBZ and 445 for EPDM.
- What are antioxidants & TPS?
- Antioxidants are widely used to improve the performance of rubber, and their production, especially 6PPD, is annually maintained at a high level . Amine antioxidants and TPs have been generally detected in the environment, especially in water, air, and dust, indicating that they can be transported through the atmosphere and rivers.
- What are the commercial products of heterocyclic antioxidants?
- The commercial products of heterocyclic antioxidants mainly include 2-mercaptobenzimidazole (MB), 2-mercaptomethylbenzimidazole (MMB), 2-mercaptobenzimidazole zinc salt (MBZ), 2-mercaptomethylbenzimidazole zinc salt (MMBZ) and the benzothiazole derivatives . Among them, MB and MBZ are the two most common products.
