rubber anti-aging agent antioxidant 6PPD (4020) supplier,6ppd is an organic chemical widely used as stabilising additive (or antidegradant) in rubbers, such as nr, sbr and br; all of which are common in vehicle tires. although it is an effective antioxidant it is primarily used because of its excellent antiozonant performance.
the tire antioxidant and antiozonant, 6ppd, is added to extend the polymer rubber lifetime. following environmental exposure, 6ppd transforms to its highly toxic quinone form n (1,3
transformation products of tire rubber antioxidant 6ppd for sale
6ppd reactions with ozone generate numerous ubiquitous and potentially bioactive transformation products that can be detected in tire rubber particles and roadway environments.
environmental profiles, hazard identification for sale,however, the environmental consequences of waste generated during rubber product use, particularly the formation of 6ppd-quinone (6ppd-q) through the reaction of 6ppd with ozone, have raised significant concerns due to their detrimental effects on ecosystems.

the study will expose fish cell lines to rubber containing three possible alternatives to 6ppd and their transformation products. the toxicity of each proposed alternative will be assessed and compared to the toxicity levels of 6ppd-quinone.
environmental fate of tire-rubber related pollutants 6ppd,To improve tire durability, the antioxidant n-(1,3-dimethylbutyl)-n-phenyl-p-phenylenediamine (6PPD) is used in rubber, but when exposed to oxidants such as ozone (O3), it is converted into toxic 6PPD quinone (6PPD-Q), causing ecological problems.
6ppd rubber antioxidant: characteristics, applications
6ppd (n-(1,3-dimethylbutyl)-n'-phenyl-p-phenylenediamine) is a highly effective rubber antioxidant with notable characteristics, including excellent heat resistance, anti-flex cracking properties, and compatibility with various rubber types.
tire-rubber related pollutant 6-ppd quinone: a review of its,exposure to 6-ppdq at environmentally relevant concentrations could induce several types of toxicity, including neurotoxicity, intestinal toxicity, and reproductive toxicity. this review also identifies and discusses knowledge gaps and research needs for the study of 6-ppdq.
tire anti-degradants (6ppd) team itrc itrc
tire anti-degradants are used to extend the life of tires by preventing the cracking and breakdown of rubber as it reacts with ozone over time. 6 p-phenylenediamine (6ppd) is currently the most prevalent chemical used for this purpose and is known to produce 6ppd-quinone (6ppd-q) through interaction with ozone. 6ppd and 6ppd-q enter the
big discount rubber antioxidant 6ppd for tyre,this study reports occurrences of five compounds derived from tire rubber, including the recently discovered transformation product 6ppd-quinone, in stormwater and snowmelt runoff in the semiarid, cold-climate city of saskatoon, saskatchewan, canada.
- Are there alternatives to 6PPD as a rubber antioxidant?
- Nevertheless, conclusive studies identifying superior alternatives to 6PPD as a rubber antioxidant remain scarce in the current literature. Urbanization has resulted in an increase in surface runoff, a phenomenon that plays a pivotal role in the transportation of chemicals originating from tire wear into aquatic environments.
- Can abiotic processes reprogramme the toxicity of 6ppd-q?
- Additionally, it was observed that during UV treatment, hydroxyl groups were detected in the transformation products of 6PPD-Q (Wang et al., 2024), indicating that abiotic processes can induce hydroxylation, potentially reprogramming its toxicity.
- Does acetone remove 6PPD from waste rubber?
- A parity plot of the measured extraction efficiency versus the calculated 6PPD solubility (Fig. 2e) corroborates that solubility is a crucial determinant of the solvent’s ability to remove 6PPD from waste rubber and confirms that acetone is one of the best solvents while being inexpensive and non-toxic.
- What are the enantiomers of 6PPD & 6ppd-q?
- It is important to note that both 6PPD and 6PPD-Q contain a chiral carbon, resulting in the presence of enantiomers: S-enantiomer of 6PPD (S-6PPD), R-enantiomer of 6PPD (R-6PPD), S-enantiomer of 6PPD-Q (S-6PPD-Q), and R-enantiomer of 6PPD-Q (R-6PPD-Q) (Di et al., 2022).
