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. [7] this process forms aminoxyl radicals [8][9] and was first thought
transformation products of tire rubber antioxidant 6ppd for sale
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. to address these data gaps, gas-phase ozonation of 6ppd was
computational studies of rubber ozonation explain the,the discovery that the commercial rubber antidegradant 6ppd reacts with ozone (o3) to produce a highly toxic quinone (6ppd) spurred a significant research effort into nontoxic alternatives. this work has been hampered by lack of a detailed understanding of the mechanism of protection that 6ppd affords rubber compounds against ozone. herein, we report high-level density functional theory

edinburgh, uk the need to replace 6ppd (n-(1,3-dimethylbutyl)-n'-phenyl-p-phenylene diamine) is not just a pressing matter for the tire industry as highlighted at rubbercon 2023 in edinburgh. at the conference, marie yrieix of hutchinson sa reported on the french industrial rubber products maker's search for alternative ways of
6ppd rubber antioxidant: characteristics, applications,6ppd (6-ppd or n-(1,3-dimethylbutyl)-n'-phenyl-p-phenylenediamine) is a widely used rubber antioxidant that plays a vital role in the production of rubber products. this article aims to provide an overview of 6ppd, its characteristics, its applications in rubber product manufacturing, potential product combinations, and important considerations for commercial procurement. 1. what is 6ppd? 6ppd
rubber antioxidant 6ppd in tires as a- rubber world
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. tire manufacturers have taken seriously the
environmental profiles, hazard identification for sale,recycled rubber, as an important area of sustainable development and resource utilization, is closely related to the environmental impacts and ecological risks of 6ppd and its transformation product 6ppd-q. 6ppd is a rubber antioxidant, which has been widely used in rubber products to prolong their service life.
global tire consortium identifies five potential 6ppd
preliminary assessment by ustma-organised consortium conducted on more than 60 initial candidates. washington a global consortium of 30 tire manufacturers has identified five potential alternatives to 6ppd as an anti-degradant for tires. mobilised by the us tire manufacturers association (ustma), the consortium members have submitted a
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. 6ppd is a more active antioxidant than quinoline or diphenylamine based antioxidants.
- What is the content of 6PPD in rubber?
- Typically, the content of 6-PPD in rubber materials ranges from 0.4% to 2% . During its production and use, 6-PPD can be transported to exposed surfaces and enter the environment. These antioxidants are highly reactive to ozone . 6-PPDQ is more stable than 6-PPD.
- What causes 6ppd-q in soil and tire rubber wear particles (TRWPS)?
- There is a linkage between 6PPD-Q in soil and tire rubber wear particles (TRWPs), indicating its origin from sources associated with vehicular activities (Klockner et al., 2019). Approximately 50% of TRWPs can infiltrate the soil, releasing bound chemicals like 6PPD (Klockner et al., 2019).
- Can abiotic processes reprogramme the toxicity of 6ppd-q?
- Additionally, it was observed that during UV treatment, hydroxyl groups were detected in the transformation products of 6PPD-Q (Wang et al., 2024), indicating that abiotic processes can induce hydroxylation, potentially reprogramming its toxicity.
