6ppd, a tire rubber antioxidant, poses substantial ecological risks because it can form a highly toxic quinone transformation product (tp), 6ppd-quinone (6ppd), during exposure to gas-phase ozone. important data gaps exist regarding the structures, reaction mechanisms, and environmental occurrence of tps from 6ppd ozonation.
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.
rubber additive rubber antioxidant 6ppd cas 793-24-8,6ppd provides powerful antiozonant and antioxidant properties with excellent high temperature, fatigue and flex resistance to rubber compounds. it gives efficient stabilization for a wide range of solution and emulsion polymers.
recent progress in the rubber antioxidants Rubber Auxiliary Agent
the authors claimed that the thermal aging resistance rubber compounds containing nr-g-ppdam were better than those containing low molecular weight antioxidant 6ppd.
environmental impact of tire wear: the 6ppd-q Rubber Antioxidant,due to the low 6ppd-q lc 50 values determined for various aquatic organisms, this tire material reuse combined with typical wear and tear of tires on active roadways could lead to significant negative impacts (and potentially extinctions) of vital, culturally significant aquatic species.
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.
environmental profiles, hazard identification for sale,n-(1,3-dimethylbutyl)-n'-phenyl-p-phenylenediamine (6ppd) is commonly used in rubber compounds as antioxidants to protect against degradation from heat, oxygen, and ozone exposure. this practice extends the lifespan of rubber products, including tires, by preventing cracking, aging, and deterioration.
eco-friendliness rubber antioxidant tmq for tire
tian et al. found that 6ppd-quinone, a derivative of tire antioxidant 6ppd, can cause acute death of silver salmon (tian et al. 2021). many recent studies have demonstrated the hazards of the extensive use of tire antioxidants.

- Is 6ppdq toxic?
- N- (1,3-dimethylbutyl)-N'-phenyl-p-phenylenediamine-quinone (6PPDQ), one of the oxidation products of rubber antioxidant 6PPD, has been identified as a novel toxicant to many organisms. However, an understanding of its underlying toxicity mechanisms remained elusive.
- Why is 6PPD the main antioxidant in tires?
- Probably because expressway service area being affected by a single vehicle source, while other areas are also affected by topsoil and multiple sources, and 6PPD is the main antioxidant in tires. Fig. 4. Functional region-dependent difference in distribution of PPDs and 6PPD-Q in road dusts from Dalian of China.
- What are the primary sources of 6PPD & 6ppd-q?
- The primary sources of 6PPD and 6PPD-Q in the environment are tire and road wear particles. In the atmosphere, 6PPD undergoes a reaction with ozone to form 6PPD-Q under conditions such as light and high temperature. In the pedosphere, the transformation of 6PPD-Q primarily occurs through heterogeneous iron reduction by microorganisms.
- Does 6ppd-q have a higher bioaccumulation than 6ppd-q?
- Notably, 6PPD-Q exhibited greater bioaccumulation than 6PPD, likely attributable to its slower clearance from the body, as evidenced by the higher urinary excretion of 6PPD compared to 6PPD-Q in mouse samples (Zhao et al., 2023c).
