rubber antioxidant 6ppd 4020 for hot sale,detail introduction. product name: ippd (4010 na) chemical name: n-isopropyl-n'-phenyl-p-phenylenediamine. cas no.: 793-24-8. product specification: -6ppd is an outstanding antioxidant and antiozonant, generally used for natural rubber and synthetic rubber. -6ppd can slow rubber’s fatigue degradation under static and dynamic operating conditions.
rubber antioxidants and their transformation products
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.
(pdf) rubber antioxidants tmq particles,antioxidants are the main rubber antioxidants produced and used in china, of which 6ppd and 2,2,4-t rimethyl-1,2-dihydroquinoline (tmq, rd) have the highest production, account- ing for more than.
The latest development of rubber antioxidants
currently, rubber antioxidants are one of the indispensable additives in the rubber industry, they enhance the service life and reliability of the rubber product by protecting it from degradation. unfortunately, antioxidative efficiency, toxicity, and blooming/migration issues, etc., have plagued the development of rubber antioxidants.
rubber antioxidants and their transformation products mdpi,antioxidants are prevalently used during rubber production to improve rubber performance, delay aging, and extend service life. 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.
rubber aging agent 6ppd(4020) national standard quality
rubber aging agent 6ppd(4020) national standard quality rubber additives high efficiency anti aging. rubber antioxidant 4020/6ppd. chemical name:n-(1,3-dimethyl-buty)-n’-phenyl-p-phenylenediamine molecular: c18h24n2 cas no.: 793-24-8. molecular weight: 268.40. hs code: 3812301000
synthesis and properties of a novel reactive and low,the addition of antioxidants to rubber is one of the most economical and effective methods for delaying rubber aging. however, antioxidant migration can cause environmental pollution. to address this issue, a new reactive antioxidant was synthesized via the chemical bonding of glycidyl methacrylate (gma) and p-aminodiphenylamine (ppda). the product was characterized by fourier-transform.
- What is the difference between antioxidants 4020 and 4010na?
- Rubber composites containing antioxidants 4020 and 4010NA were immersed and extracted, resulting in solutions that were noticeably darker in color than those of the rubber composites with GMA-PPDA antioxidants, which had also been immersed.
- 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 oxidative aging of rubber?
- Thermal oxidative aging is the most frequent type of rubber degradation. To delay or prevent this process, antioxidants can be added to rubber compounds during mixing. (9) Antiaging agents react primarily with the free radicals or hydrogen peroxide generated during rubber aging.
- Are rubber antioxidants effective against aging and antimigration?
- The antiaging and antimigration properties of the rubber antioxidants were enhanced without damaging the mechanical properties of the rubber matrix. The short-term and long-term antiaging and antimigration properties of this antioxidant are superior to those of commercially available antioxidants. CC-BY-NC-ND 4.0 . 1. Introduction
