addressing durability of rubber compounds rubber chemistry,although conventional antidegradants such as n-isopropyl-n'-phenyl-p-phenylenediamine (ippd) and n-(1,3-dimethylbutyl)-n'-phenyl-p-phenylenediamine (6ppd) are still the most widely used antidegradants in rubber, there is a trend and demand for longer-lasting and non-staining products.
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.
rubber antioxidants and their transformation products
a film-isolating oxygen and o 3 is formed on the surface of rubber products by directly applying or spraying, which can prevent the rubber from aging. by contrast, chemical antioxidants are usually used to address the reaction stage of rubber aging.
enhancing rubber performance with antioxidant ippd,this article will introduce the excellent antioxidant properties of rubber antioxidant ippd and its important role in improving the performance of rubber products, providing valuable information and insights for relevant practitioners in the industry.

in this study, we chose natural rubber (nr) as a matrix and provided a screening strategy based on diverse natural phenolic antioxidants to evaluate their ability in protecting nr composites. thymol, α-tocopherol, and lipid-soluble epigallocatechin gallate (lsegcg) were chosen from 18 natural phenolic antioxidants as potential alternative
rubber antioxidants and chemical 6ppd,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
zirconium phosphate modified by polydopamine as anti-aging
herein, we prepared a green anti-aging composite filler called zpa via an in situ intercalation polymerization procedure of polydopamine (pda) on zirconium phosphate (α -zrp) for realizing the enhancement of mechanical performance and aging resistance in nitrile butadiene rubber (nbr).
anti-aging performance advantages of rubber antioxidant ippd,explore the comparative analysis of rubber antioxidant ippd (n-isopropyl-n'-phenyl-p-phenylenediamine) with other antioxidants in this comprehensive review. learn about the anti-aging advantages, diverse application fields, and cost-effectiveness of ippd in the rubber manufacturing industry.

recent progress in the rubber antioxidants Rubber Auxiliary Agent,the anti-aging behavior of styrene-butadiene rubber (sbr)/silica with cos-gmmp, as well as the low molecule antioxidant gm, was systematically investigated by the accelerated thermal...
- 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].
- 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.
- 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 .
- 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.
