chemical industry antioxidant TMQ/RD for sale,abstract. the substituted p -phenylenediamines (ppds) represent a suite of effective antioxidants broadly applied in rubber industries. however, knowledge of their environmental occurrences and fate remains extremely limited.
from tread to watershed: how tire wear particle chemicals
the environmental ubiquity of tire and road wear particles (trwp) underscores the need to understand the occurrence, persistence, and environmental effects of tire-related chemicals in aquatic ecosystems. one such chemical is 6ppd-quinone (6ppd-q), a transformation product of the tire antioxidant 6ppd.
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.
- 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 a dangerous hazard?
- Various aquatic species have shown severe susceptibility to 6PPD-Q 3, 4. 6PPD has been detected in humans 5 and causes severe developmental, physical deformative and behavioral health effects 6. Crumb rubber derived from EOL tires is used in asphalt and recreational fields, with 6PPD shown to leach from these spaces 7.
- Does Hildebrand acetone have a higher boiling point than 6PPD?
- Hildebrand solubility parameters were also investigated but did not show a well-defined trend (Supplementary Fig. 14 and Supplementary Table 3). Acetone’s lower boiling point (56 °C) compared with 6PPD (260 °C) makes solvent recovery much less energy intensive.
