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.
6ppd reactions with ozone generate numerous ubiquitous and potentially bioactive transformation products that can be detected in tire rubber particles and roadway environments.
transformation products of tire rubber antioxidant 6ppd for sale
abstract: 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.
u.s. tire manufacturers association and u.s. geological,6ppd is an antiozonant (chemical) and antioxidant present in all motor vehicle tires on u.s. roads. the chemical serves critical safety and performance functions that protect motor vehicle tires from degradation upon exposure to ozone and oxygen in the air.
big discount rubber antioxidant 6ppd for tyre
by investigating this phenomenon, we identified a highly toxic quinone transformation product of n-(1,3-dimethylbutyl)-n'-phenyl-p-phenylenediamine (6ppd), a globally ubiquitous tire rubber antioxidant.
Best Price Rubber Antioxidant 6PPD CAS No.: 793-24-8,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...
rubber antioxidants and their transformation products
recently, it was reported that the rubber antioxidant n-(1,3-dimethylbutyl)N'-phenyl-p-phenylenediamine (6ppd or antioxidant 4020), a typical tire rubber antioxidant, could enter the surrounding environment together with tire-wear particles (twps).
6ppd in tire manufacturing ustma,safety is at the core of everything tire manufacturers do and the complex blend of rubber compounds and materials in our products is designed to withstand a wide range of demanding conditions. 6ppd serves an essential safety function in tires as an antioxidant and antiozonant, protecting the components of the tire from attack by ozone, oxygen
rubber antioxidant 6ppd in tires as a priority product
ustma and its member companies recommended adding 6ppd to the priority products work plan immediately following the december 2020 tian et al. study that suggested a link between coho salmon mortality and a transformation product of 6ppd from tire and road wear particles (trwp) called 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.
- Is 6PPD in tires a priority product?
- DTSC designates 6PPD in tires as a Priority Product and USTMA expands its consortium to 32 tire manufacturers from around the world to prepare a Preliminary (Stage 1) Alternatives Analysis (AA) to identify and evaluate potential alternatives to 6PPD in tires. Individual consortium members submitted the report to DTSC to meet compliance deadline.
- Is there an alternative to 6PPD in tires?
- Today there is no commercially available alternative to 6PPD that both provides comparable safety and performance in motor vehicle tires and minimizes potential environmental effects. 6PPDQ Identified | USTMA requests DTSC review 6PPD in tires
- Are Tire-Rubber pollutants harmful to human health?
- 2. Future research will prioritize assessing the ecological and human health risks associated with tire-rubber related pollutants since it has been detected in human urine (Du et al., 2022). This includes going into the ecological repercussions on soil ecosystems, plant health, and terrestrial as well as aquatic food webs.
- 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.
