Antioxidants
Antioxidants. Virtually all polymeric materials undergo oxidation reactions. Oxidation can occur at every stage of the life cycle of a polymer, i.e. during manufacturing and storage of the material or during processing and end-use. Typical manifestations of oxidation of polymers can be change of viscosity during processing, appearance, and loss

environmentally friendly epoxy soybean oil esbo plasticizer
Epoxidized soybean oil (ESBO) is a clear to yellow liquid. ESBO is industrially available in large volume at a low price. Due to its low cost, non-toxicity and environmentally friendly properties, as well as its biodegradability compared to traditional phthalate plasticizers, ESBO is replacing dioctyl phthalate (DOP) in some applications.

- Are rubber antioxidants harmful to the environment?
- 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 and their TPs.
- 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 .
- Does antioxidant 2246 protect rubber from aging?
- Among them, antioxidant 2246 has a good performance to protect rubber from aging caused by heat, oxygen, and metals. Because hydrogen in phenolic antioxidants can combine with the oxygen in air, their antiaging efficiency is therefore lowered compared with amine antioxidants [21, 22].
- 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.
- Why are chemical antioxidants used in rubber aging?
- By contrast, chemical antioxidants are usually used to address the reaction stage of rubber aging. According to the different fracture modes of the molecular chain of raw rubber materials, different chemical antioxidants are added to block the growth reaction chain during aging .
