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 antioxidant tmq, tq, tdq, rd manufacturer
mernox tq is classified as a staining type, low volatility, and polymeric antioxidant with very high potency. mernox tq, does not contribute to flex fatigue resistance and hence generally used in combination with para phenylenediamine class antidegradants like mernox 6c. mernox tq is also effective with metal ion catalysed degradation.

occurrence of substituted p-phenylenediamine antioxidants in dusts,the substituted p-phenylenediamines (ppds) represent a suite of effective antioxidants broadly applied in rubber industries. however, knowledge of their environmental occurrences and fate remains extremely limited. herein, we explored the occurrence of six major ppd antioxidants and one newly defined transformation product in dust particles from different environments, including roads.
- 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.
- 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 .
- 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.
