technical data sheet rhenogran predispersed rubber chemicals
mode of action: rhenogran mmbi-70 is mainly used as a synergist for other antioxidants. the effect of the combination of rhenogran mmbi-70 with other antioxidants is always greater than the sum of the effects of the individual components. rhenogran mmbi-70, used on its own is a moderately powerful, non-staining 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.

westcotm mmbi 4-and5-methyl-2-mercaptobenzimidazole cas,characteristics: westcotm mmbi (mmb) is a non-discoloring, non-staining secondary antioxidant for natural and synthetic rubbers with exception to polychloroprene. it is particularly effective when used in combination with other westco antioxidants and is well suited for light colored or white compounds.
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.
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.

- 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 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.
- 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 .
- 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.
- 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 rubber products used for?
- Rubber products are mainly used in industrial and agricultural production, transportation, and national defense construction, and antioxidants are a group of the most important chemicals with widespread use in rubber products.
