a nation-wide study for the occurrence of ppd antioxidants,the present study presents a snapshot for the distribution characteristics of ppds and 6ppd-q in road dusts of major cities in china. three kinds of antioxidants 6ppd, dnpd and dppd were the dominant ppds in sampled road dusts. as ozonation product of 6ppd, 6ppd-q had the highest proportion in most road dusts.
here, we analyzed tire wear particles (twps), recycled rubber doormats, and turf-field crumb rubbers for seven ppd antioxidants, five ppd-quinones (ppdqs), and five other 6ppd tps using liquid chromatography-tandem mass spectrometry.

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.

first report on the occurrence of n-(1,3-dimethylbutyl)-n,both 6ppd and 6ppd-q were detected in the urine samples, with detection frequencies between 60% and 100%. urinary 6ppd-q concentrations were significantly higher than those of 6ppd and correlated well with those of 6ppd (p < 0.01), indicating coexposure to 6ppd and 6ppd-q in humans.

6ppd-q in human samples highlight the need for further research on public health. abstract. 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.
rubber antioxidants and their transformation products,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.
widely used good price rubber antioxidant ippd
n-(1,3-dimethylbutyl)-n'-phenyl-p-phenylenediamine (6ppd) is the most widely used antioxidant in automobile tyres and many rubber products. we investigated the impact of 6ppd and 6ppd quinone on acute toxicity, morphol., swimming behavior, heart rate, and oxygen consumption in zebrafish larvae.
rubber antioxidant 6PPD price antioxidant 4020,abstract: recently, roadway releases of n,n′-substituted p-phenyl-enediamine (ppd) antioxidants and their transformation products (tps) received significant attention due to the highly toxic 6ppd-quinone. however, the occurrence of ppds and tps in recycled tire rubber products remains uncharacterized.
- What is 6PPD & 6qdi?
- Keywords: 6PPD; 6QDI; N-oxide; air; ozone; roadway environments; tire tread wear particles. 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.
- 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.
- Is 6ppd-q a risk factor for aquatic organisms?
- 6PPD-Q and 6PPD were the dominant components in road dusts. The median concentration of 6PPD-Q in urban trunk road dusts was 49.4 ng/g. PPDs and 6PPD-Q showed traffic functional region-dependent differences. Runoff potential assessment indicate the risk of 6PPD-Q to aquatic organisms.
- 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.
