high energy rubber anti-degradation agent mb (mbi),rubber anti-degradation agent mb (mbi), scientific name is 2-mercapto benzimidazole, molecular formula is c7h6n2s, cas number is 583-39-1. mb (mbi) is a white powder, odorless, with good stable storage ability, widely used in natural rubber, chloroprene rubber (cr), polystyrene (sbr), nitrile rubber (nbr) and ethylene propylene rubber (epr) as a non-toxic secondary antioxidant.
rubber antioxidants and their transformation products
natural antioxidants are only found in nr, such as amino acids, tocotrienol, and betaines , whereas physical and chemical antioxidants are widely used in various synthetic rubber products. the rubber-aging process comprises three stages: initiation, reaction, and termination [ 15 , 16 ], and the physical antioxidants are usually used to address.
Rubber Antioxidant Mbz CAS. No: 3030-80-6 price,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.

antioxidants rubber mbi chemical indiamart. accinox mbi as such is seldom used in the rubber industry as it inhibits little ageing properties in rubber compounds; accinox mbi is used primarily as synergistic additive for other antioxidants of both amine and phenolic types especially in improving heat ageing resistance and countering metallic contaminations
rubber additive predispersed rubber chemicals zdbc rubber vulcanizing agents,mode of action: rubber additive mmbi-70 is mainly used as a synergist for other antioxidants. the effect of the combination of rubber additive mmbi-70 with other antioxidants is always greater than the sum of the effects of the individual components. rubber additive mmbi-70, used on its own is a moderately powerful, non-staining antioxidant.

recent progress in the rubber antioxidants: a review
the commonly used rubber antioxidant can be divided into primary antioxidant and secondary antioxidant according to the anti-aging mechanism [13]. the primary antioxidants, such as aryl amines and phenolic antioxidants, could inhibit the propagation reaction by supplying the reactive hydrogen atom to the free radicals.

- 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.
- 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.
- 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.
- Which antioxidants are used in rubber vulcanization?
- The amine and phenolic antioxidants are the most widely used rubber antioxidants (Fig. 1 b and c). Generally, the phenolic antioxidants have poor antioxidative efficiency (compared to amine antioxidants) and they can delay vulcanization, but they cause little discoloration problems.
- 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 future trends of rubber antioxidants?
- The perspectives on the future trends of rubber antioxidants have been presented. Elastomers, especially diene-rubbers containing unsaturated double carbon bonds in the main chains, are vulnerable to thermal/oxygen aging, which would make the elastomers less elastic and result in earlier failure of the elastomer products.
