end-of-life tire decontamination from 6ppd and upcycling nature,abstract. n (1,3-dimethylbutyl)- n ′-phenyl- p-phenylenediamine (6ppd) is a ubiquitous rubber antioxidant and antiozonant that extends the lifetime of common rubber products, such as those.
as we advance into 2024, the role of antioxidants in rubber manufacturing remains crucial. one such critical antioxidant is n-(1,3-dimethylbutyl)-n'-phenyl-p-phenylenediamine (6ppd). this article provides a comprehensive overview of 6ppd, comparing it with other rubber antioxidant types and discussing their applications in various industries.

antioxidant 4020 rubber additives 6ppd in tires,with full support from ustma, dtsc listed motor vehicle tires containing 6ppd as priority products in california effective october 1, 2023. to meet the requirements under the scpr, ustma convened a consortium of 32 tire manufacturers to conduct an aa for 6ppd in tires. the preliminary (stage 1) aa report was released by ustma and submitted by.
transformation products of tire rubber antioxidant 6ppd price
6ppd, a tire rubber antioxidant, poses substantial ecological risks because it can form a highly toxic quinone transformation product (tp), 6ppd-quinone (6ppdq), during exposure to gas-phase ozone. important data gaps exist regarding the structures, reaction mechanisms, and environmental occurrence of tps from 6ppd ozonation. to address these data gaps, gas-phase ozonation of 6ppd was.
rubber plastic additives antioxidant 6ppd,antioxidant 6ppd (4020) 6ppd is a strong antioxidant that is used as an antioxidant and antioxidation agent in rubber production. this substance has low toxicity and prevents polymer corrosion and increases the stability of the final product.

6ppd chemical active antioxidant,6ppd is a common rubber antiozonant found in vehicle tires. it is mobile within the rubber and slowly migrates to the surface via blooming. on the surface it forms a "scavenger-protective film" that reacts with the ozone more quickly than the ozone can react with the rubber. this process forms aminoxyl radicals and was first thought.

sunlight-induced transformation of tire rubber antioxidant n,the huge consumption of the tire rubber antioxidant n-(1,3-dimethylbutyl)-n′-phenyl-p-phenylenediamine (6ppd) has resulted in pervasive contamination in aquatic environments. more importantly, the transformation product of 6ppd, i.e., 6ppd-quinone (6ppd-q), is raising increasing concerns due to its high toxicity to aquatic organisms. however, whether and how 6ppd-q can be formed from 6ppd in.
- Does 6PPD ozonation pose environmental risks?
- 6PPD, a tire rubber antioxidant, poses substantial ecological risks because it can form a highly toxic quinone transformation product (TP), 6PPD-quinone (6PPDQ), during exposure to gas-phase ozone. Important data gaps exist regarding the structures, reaction mechanisms, and environmental occurrence of TPs from 6PPD ozonation.
- Can 6PPD be recycled?
- We demonstrate the catalytic upgrade of 6PPD to safe chemicals and the valorization of crumb rubber to aromatics and carbon black using microwave-assisted pyrolysis. Upcycling end-of-life tire waste is complex due to the recalcitrant nature of the toxic legacy additive, 6PPD.
- Does 6PPD survive microwave-assisted pyrolysis?
- With legislation on the horizon to ban 6PPD entirely, developing effective methods for its removal and conversion to safe compounds is essential. Here we show that 6PPD survives microwave-assisted pyrolysis and escapes in the oil product, rendering decontamination essential.
- Does 6PPD survive pyrolysis?
- The liquid pyrolysis oil product distribution and solid carbon black powder from the 1.3 mm and 0.6 mm particles are independent of the starting particle size (Fig. 1d); however, gas chromatography–mass spectrometry (GC–MS) of the oil product shows that 6PPD survives appreciably after pyrolysis (Supplementary Fig. 10).
