new evidence of rubber-derived quinones in water, air for sale,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.
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.
6ppd rubber antioxidant: characteristics, applications
6ppd (n-(1,3-dimethylbutyl)-n'-phenyl-p-phenylenediamine) is a highly effective rubber antioxidant with notable characteristics, including excellent heat resistance, anti-flex cracking properties, and compatibility with various rubber types.
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
environmental profiles, hazard identification for sale
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. this practice extends the lifespan of rubber products, including tires, by preventing cracking, aging, and deterioration.
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.

rubber antioxidants: tmq, 6ppd, ippd chemical products,tmq, also known as polymerized 2,2,4-trimethyl-1,2-dihydroquinoline, is a widely used rubber antioxidant. it provides excellent protection against heat, oxygen, and flex-cracking, enhancing the durability and performance of rubber products.
a tire industry perspective on 6ppd replacement: the challenge
to act like 6ppd, a drop-in substitute must: function as antiozonant and antioxidant to help prevent the degradation and cracking of rubber compounds (unsaturated elastomers) by protecting against ozone attack, oxidation, and heat aging.
6ppd rubber antioxidant new markers for sale,the pollution level of ppds in pm 2.5 exhibited significant variability across years. notably, 6ppd, a dominant species of ppds, demonstrated a substantial increase, with concentrations from 2017 to 2020 being 1.30, 3.72, 7.10, and 8.85 times higher than those in 2016 (fig. 2 c, table s5).
- 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.
- Are p phenylenediamine (PPD) antioxidants in recycled tire rubber products toxic?
- Recently, roadway releases of N, N ′-substituted p -phenylenediamine (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.
- Are PPD antioxidants present in all samples dominated by 6PPD and dtpd?
- PPD antioxidants, PPDQs, and other TPs were present in all samples with chemical profiles dominated by 6PPD, DTPD, DPPD, and their corresponding PPDQs.
- Does 6ppd-q affect SNA oxidation rate?
- A significant negative correlation was observed between 6PPD-Q and SNA. Moreover, there are also significant negative correlations between the 6PPD-Q and nitrogen oxidation rate, as well as sulfur oxidation ratio, illustrating the potentially competitive formation mechanism between SNA and 6PPD-Q.
