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.
antioxidant at 0.4−2% by weight,33 where it is designed to quickly react with ground-level o 3 to protect rubber elastomers.34,35 such reactions inevitably form other trans-formation products (tps) beyond 6ppdq during the tire rubber lifetime.21,34 for example, early studies on the antioxidant ecacy of 6ppd (e.g., lattimer et al.) proposed

rubber antioxidants crossland chemicals
6ppd is a general antioxidant and antiozonant, which is suitable for the formulations of natural rubber and synthetic rubber. it can be applied to tires, conveyor belts, rubber pipes, cables, etc., and rubber products that need dynamic and static oxidation and ozone resistance protection. 6ppd has a stabhization effect on many solution and.
The latest development of rubber antioxidants,generally, the primary antioxidants and secondary antioxidants can be used together to protect the rubber as they could have a synergistic antioxidant effect, i.e., the primary antioxidant could be used as the chain-breaking donor type to capture the free radical during the oxidation-aging period and the secondary antioxidant could react with.

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.
6ppd rubber antioxidant: characteristics, applications,6ppd is an organic compound belonging to the p-phenylenediamine class of antioxidants. it is a dark purple solid with a slight odor. chemically, it consists of n- (1,3-dimethylbutyl)-n'-phenyl-p-phenylenediamine molecules. 6ppd is known for its solubility in rubber and compatibility with various types of rubber. 2.
- 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 .
- 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.
- Do Antioxidants improve the performance of rubber?
- Conclusions and Future Perspectives Antioxidants are widely used to improve the performance of rubber, and their production, especially 6PPD, is annually maintained at a high level .
- 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.
