logp: 3.9 at 25℃ epa chemical information : information provided by: ofmpub.epa.gov (external link) overview : 2,2, 4-trimethyl-1, 2-dihydroquinoline polymer, alias antioxidant rd in chinese, with cas number 26780-96-1, is an industrial catalyst plastic rubber additive. 2,2,4-trimethyl -1,2-dihydroquinoline polymer chemical formula c36h45n3, molecular weight 519.76300, melting point 2-94°c.
novel antioxidants based on polymerized 2,2,4-trimethyl-1,2,novel antioxidants based on polymerized 2,2,4-trimethyl-1,2-dihydroquinoline (tmq) are synthesized. tmq is chemically modified to obtain new derivatives, namely; ester, hydarzide, oxadiazole and triazole. the synthesized polymers are characterized by fourier transforms infrared spectroscopy (ftir) and proton-nuclear magnetic resonance (1hnmr). the formed polymers are evaluated as antioxidants.
rubber antioxidants: tmq, 6ppd, ippd price
antioxidant 6ppd (4020) 6ppd, or n-1,3-dimethylbutyl-n’-phenyl-p-phenylenediamine, is a synthetic rubber antioxidant widely used in the tire and rubber industry. it provides protection against degradation caused by heat, oxygen, and flex-cracking. 6ppd acts as a stabilizer and antiozonant, preventing the formation of harmful free radicals and.

2024 professional guide to rubber antioxidant tmq
rubber antioxidant tmq is a high-quality rubber stabilizer that helps to increase the life of synthetic rubber and natural rubber. the product is produced by mixing the rubber antioxidant with other additives to form a homogeneous mixture, which is then applied to the surface of rubber products.
recent progress in the rubber antioxidants price,fig. 5 shows the chemical structures for typical low molecular weight antioxidants (fig. 5 a–e) and high macromolecular weight antioxidants (fig. 5 f–m) reported in the literature. compared to the low molecular antioxidant, the macromolecular antioxidant cannot easily migrate from the rubber to the surface because the diffusion coefficients.
antioxidant rd (tmq) (high) chemical supplier
antioxidant rd (tmq) (high) by kemai chemical is 2, 2, 4-trimethyl-1, 2-dihydroquinoline. it acts as an antioxidant. it can be used as a general purpose ammonia anti aging agent. it is suitable for full-steel, semi steel and radial tires.
safe protection against oxidation lanxess,lanxess markets the antioxidant tmq (2,2,4-trimethyl-1,2-dihydroquinoline) under the trade name vulkanox hs for the production of tires and heavy-duty technical rubber goods. to manufacture this important rubber chemical, lanxess has expanded the capacities of its world-class facilities at its sites in brunsbuettel, germany, and jhagadia, india.
- Is TMQ a good antioxidant?
- TMQ (2,2,4-trimethyl-1,2-H-dihydroquinoline) is an important antioxidant because of relatively low price and ease of application in rubber production technologies. However, due to the limited experimental data and unclear reaction mechanism, the quality of the TMQ product needs to be improved in industry processes.
- Is polymerized TMQ an antioxidant?
- One of the mostly used antioxidants is polymerized TMQ. It is a secondary amine and can strongly inhibit the oxidation reactions of rubber [16, 17, 18]. Zidan et al. prepared galloyl hydrazide and used it as antioxidant for natural rubber (NR).
- Can polymerized TMQ reduce rubber oxidation?
- The addition of polymerizable antioxidants is one of the most preferable methods to overcome rubber oxidation [14, 15]. One of the mostly used antioxidants is polymerized TMQ. It is a secondary amine and can strongly inhibit the oxidation reactions of rubber [16, 17, 18].
- Is TMQ a methyl analogue?
- Owing to the relevance of TMQ and also its methyl analogues, we described the novel approach to the synthesis of important 1,2-DHQ derivatives with the use of selected sulfonic acid silica catalysts. The detailed structural analysis of reaction products have been presented for the first time.
