New phenylenediamine antiozonants for commodities based
For protection of elastomeric materials against ageing, antioxidants such as UV-stabilizers and antiozonants are used. Although historically N-phenyl-N'-(1,3-dimethylbutyl)-p-phenylenediamine (6PPD) was the only approved antiozonant in Germany, a range of other phenylene diamine antiozonants (excluding 6PPD) are permitted for use in rubber articles intended for repeat food
1. Introduction. N-(1,3-dimethylbutyl)-N′-phenyl-p-phenylenediamine or 6PPD is an antioxidant and antiozonant that is widely consumed by the rubber and polymer industry (Datta et al., 2007).This compound is mainly used in rubber tires to protect them from cracking that results from ozone reaction and wear out. 6PPD is also used to prepare dyes (Meyer and Fischer,
6PPD Wikipedia
6PPD. Except where otherwise noted, data are given for materials in their standard state (at 25 °C [77 °F], 100 kPa). 6PPD is an organic chemical that is widely used as an antiozonant and antioxidant in rubber tires. It is one of several p -phenylenediamine (PPD) additives used to protect various rubber materials.

The product under consideration is Rubber Chemicals PX-13 also known as 6PPD, antioxidant 6PPD, Kumanox 13, Santoflex 6PPD, Sirantox 6PPD, Vulkanox 4020, Antioxidant 4020, Dussantox 6PPD, Antage 6C, N-1, 3-Dimethylbutyl-N-Phenyl-P-Phenylenediamine, etc. PX-13 is an alkyl-aryl-PPD antidegradant most widely used in the tyre and non tyre sector of
Oct 15, 2021· Analysis of the solution using the 6PPD obtained commercially as a standard indicated that approximately 50% (9.31 × 10 −4 mol) of the original 500 mg of 6PPD was unreacted, so the amount 6PPD-q present in the solution was estimated to be 278 mg. Using this estimate, the amount of 6PPD-q in the standard was approximated and a calibration
FLEXSYS AMERICA LP v. Kumho Tire USA, Inc., 726 F. Supp
Flexsys's Product Data sheet for 6PPD describes 6PPD as "a powerful antioxidant and antiozonant for natural and synthetic elastomer compounds and as a synthetic polymer stabilizer." (Fu Decl. at ¶ 9, Ex. D.) The Product Data sheet further provides that 6PPD exhibits "excellent high temperature, fatigue and flex resistance to rubber compounds
Within the textiles and fillers lies a little-known chemical compound called 6PPD, the primary antioxidant chemical used in tires. When combined with ozone, it forms what's known as 6PPD-quinone.

- What is 6PPD used for?
- 6PPD is widely produced and used in many commercial rubber products; including car tyres, rubber hoses and belts. These chemicals offer exceptional protective capabilities for safeguarding rubber products from heat deterioration, degradation, and ozone-induced cracking, working as antioxidants .
- Is 6PPD a good antiozonant?
- With the effect of ozone, 6PPD is converted to 6PPD quinone, which is toxic enough to kill some sensitive fish species such as Coho Salmon (Oncorhynchus kisutch). This study drew attention to new chemical compounds and natural products that can be used as antiozonants and antioxidants in the rubber industry instead of 6PPD.
- Do substituted para phenylenediamine (PPD) antioxidants affect the environment?
- 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.
- What are antioxidants & TPS?
- Antioxidants are widely used to improve the performance of rubber, and their production, especially 6PPD, is annually maintained at a high level . Amine antioxidants and TPs have been generally detected in the environment, especially in water, air, and dust, indicating that they can be transported through the atmosphere and rivers.
- Is 6PPD toxic?
- It is widely used in the motor vehicle tire and general rubber goods sector. Washington State Department of Ecology considers 6PPD as a toxicant of high concern due to aquatic toxicity, reproductive toxicity, environmental persistence, and bioaccumulation potential.
- What are antiozonants & antioxidants?
- Antiozonants and antioxidants are additives commonly used in the rubber industry to enhance the durability and performance of rubber products. Ozone, present in the atmosphere, can cause rubber to degrade over time through a process known as ozone cracking. These rubber additives are added to rubber compounds to protect against this degradation.
