environmental impact of tire wear: the 6ppd-q Rubber Antioxidant,the compound 6ppd (short for 1,4-benzenediamine, n-(1,3-dimethylbutyl)- 21 n’-phenyl-; cas #793-24-8) is an antioxidant and antiozonant that prevents degradation of rubber compounds caused by their exposure to oxygen, ozone and temperature fluctuations. 6ppd is widely used in the tire manufacturing industry to help tires resist degradation
6ppd serves an essential safety function in tires as an antioxidant and antiozonant, protecting the components of the tire from attack by ozone, oxygen and other factors, which is why all motor vehicle tires on the road today contain 6ppd.
rubber antioxidants: tmq, 6ppd, ippd chemical products
rubber antioxidant IPPD, or n-isopropyl-n'-phenyl-p-phenylenediamine, is a synthetic rubber antioxidant widely used in the tire and rubber industry. It prevents degradation caused by heat, oxygen, and flex cracking.
p-phenylenediamines and p-phenylenediamine quinone,in addition to wear of rubber tires, our research indicates that rubber coatings on cables and daily use of rubber consumer products also release ppds and ppd-qs, which requires attention. we describe a three-step oxidation scheme for the conversion of 6ppd to 6ppd-q in the environment.
recent progress in the rubber antioxidants Rubber Auxiliary Agent
we first give a brief introduction of the oxidation process and oxidation mechanism for rubbers. then, we present the strategies to improve the anti-oxidative efficiency of rubber antioxidants. after that, recent advances to minimize the blooming and migration of antioxidants are summarized.
transformation products of tire rubber antioxidant 6ppd for sale,6ppd reactions with ozone generate numerous ubiquitous and potentially bioactive transformation products that can be detected in tire rubber particles and roadway environments.
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).
widely used good price rubber antioxidant ippd,substituted para-phenylenediamine (ppd) antioxidants have been extensively used to retard oxidative degradation of tire rubber and were found to pervade multiple environmental compartments. however, there is a paucity of research on the environmental occurrences of their transformation products.
big discount rubber antioxidant 6ppd for tyre
automobile tires require functional rubber additives including curing agents and antioxidants, which are potentially environmentally available from tire and road wear particles (trwp) deposited in soil and sediment.
rubber antioxidants and chemical 6ppd,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).
- 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.
- Can 6PPD be removed from end-of-life tires?
- We introduce a decontamination strategy that removes 6PPD from end-of-life tires before it enters the broader ecosystem. 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.

- 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
- Does ustma use 6PPD?
- 6PPD is currently used in all USTMA member passenger, light truck, truck and bus radial, and motorcycle tires. USTMA is not aware of any new motor vehicle tires available today that do not contain 6PPD.
