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.
Rubber antioxidant 6ppd, n-1,3-dimethylbutyl-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. 6ppd acts as a stabilizer and antiozonant, preventing the formation of harmful free radicals and extending service life

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.
rubber antioxidants crossland chemicals
6ppd is a general antioxidant and antiozonant, which is suitable for the formulations of natural rubber and synthetic rubber. it can be applied to tires, conveyor belts, rubber pipes, cables, etc., and rubber products that need dynamic and static oxidation and ozone resistance protection. 6ppd has a stabhization effect on many solution and
Best Price Rubber Antioxidant 6PPD CAS No.: 793-24-8,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.
rubber antioxidants and their transformation products
as one of the widespread rubber antioxidants, amine antioxidants (ppds: tmppd, dppd, 6ppd, and 6ppdtz) could react with o 3 (in parts per billion volume levels) in the environment and produce ppd-quinone .
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 Antiageing Antiage Antioxidant 4020/6PPD price
this study revealed that sunlight-induced transformation of 6ppd could be an important origin of 6ppd-q in aquatic environments, providing significant insights to the potentially underestimated ecological risks of 6ppd.
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.
- 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.
- Why is acetone better than 6PPD?
- Acetone’s lower boiling point (56 °C) compared with 6PPD (260 °C) makes solvent recovery much less energy intensive. Although acetone can readily dissolve many classes of molecules 25, it does not degrade the cross-linked rubber phase. This is crucial for producing a 6PPD-free crumb rubber product that is safe for various applications.
- 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.
