recent progress in the rubber antioxidants price,in this review, we summarized the recent advances in rubber antioxidants over the last 10 years and offered some perspectives to outline the challenges and future research directions for the rubber antioxidants. 2. brief introduction of the oxidation process and oxidation mechanism of the rubbers.
rubber antioxidant tmq(rd); cas no. 26780-96-1 ; molecular formula: c12h15n; other synonyms: 2,2,4-trimethyl-1,2-dihydroquinoline description rubber antioxidant tmq is a versatile product that offers several benefits to manufacturers of rubber products.
high quality antioxidant tmq for sbr and sbs
antioxidant tmq is a highly effective polyphenolic additive with high activity and very low volatility. antioxidant tmq is non-discolouring and non-pinking.antioxidant tmq is especially recommended for the protection of natural and synthetic polymers based on isoprene and butadiene chemistry.
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.
environmental chemical rubber antioxidants
2.1. amine antioxidants amine antioxidant is the most common rubber antioxidant, which was produced as early as the 1970s and widely used in the rubber industry. typical amine antioxidants include diaryl-secondary amine, acetone-amine condensation product, p-phenylenediamine, and aldehyde-amine condensation product antioxidants [].

relationship between the aging thermal oxygen and mechanical properties,however, antioxidant rd is still a small-molecule compound, especially in high-temperature liquid environments, and easily migrates out of rubber matrices [7], considerably reducing the protection efficiency of antioxidants and polluting the surrounding [8].
the power of antioxidant agent rd(tmq) cost
antioxidant agent rd(tmq) is a polymerized amine derivative, predominantly used to protect rubber and rubber-based products from oxidative degradation. its primary function is to inhibit the adverse effects of oxygen and ozone exposure, preventing deterioration and maintaining the integrity of the material.
effectiveness of different kinds of antioxidants in resin‐cured,the antioxidants investigated belonged to different chemical classes such as p-phenylene diamine (antioxidant 4010na), secondary amine (antioxidant 445), quinoline (antioxidant rd), and phenolic (antioxidants bht, 1010, and 2246).
- 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.
- What are the different types of antioxidants in rubber?
- Chemical antioxidants are generally classified as amine, phenolic, heterocyclic, phosphite, and nickel salts (nickel dibutyl dithiocarbamate (NBC)) antioxidants according to their chemical structure (Figure 1). During the rubber production, various antioxidants are often used as a mixture to improve performance and ensure an antiaging effect.
- What are amine antioxidants in rubber?
- Amine antioxidant is the most common rubber antioxidant, which was produced as early as the 1970s and widely used in the rubber industry. Typical amine antioxidants include diaryl-secondary amine, acetone-amine condensation product, p -phenylenediamine, and aldehyde-amine condensation product antioxidants .
- What are the TPS of rubber antioxidants?
- 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 .
