What is 6PPD Rubber Antioxidant CAS 793-24-8?

6PPD is N-(1,3-dimethylbutyl)-N'-phenyl-p-phenylenediamine, a p-phenylenediamine antidegradant used in rubber compounds. It is widely marketed in the rubber industry as Antioxidant 4020 and is supplied as an antioxidant and antiozonant.

Is 6PPD the same material as 6PPD-quinone?

No. 6PPD-quinone is an oxidation transformation product formed from 6PPD and has a different chemical identity. It should not be treated as a synonym or substitute for 6PPD in a rubber formulation.

How does 6PPD protect rubber compounds?

6PPD acts as an antiozonant and antioxidant by helping prevent ozone attack, oxidative degradation and flex cracking in dynamic rubber parts. It is especially useful in applications exposed to continuous or intermittent stress and outdoor conditions.

Where is 6PPD commonly used?

6PPD is used in pneumatic tire compounds, conveyor and transmission belts, hoses, seals, gaskets and vibration-control components. It is also added to natural-rubber and synthetic-rubber masterbatches where a p-phenylenediamine antiozonant is specified.

Product Description

6PPD CAS 793-24-8 is N-(1,3-dimethylbutyl)-N′-phenyl-p-phenylenediamine, with EC 212-344-0 and molecular formula C18H24N2.

Synonyms: 6PPD; Antioxidant 4020; N-(1,3-Dimethylbutyl)-N′-phenyl-p-phenylenediamine; N-(4-Methyl-2-pentyl)-N′-phenyl-1,4-phenylenediamine.

CAS: 793-24-8.

Molecular formula: C18H24N2.

It is supplied as violet-brown pellets, pastilles or granules.

It is positioned as a p-phenylenediamine rubber antidegradant used as an antioxidant and antiozonant.

It is identified as 6PPD itself, not its oxidation product 6PPD-quinone.

It is used in pneumatic tire compounds, including selected tread, sidewall and carcass-related systems.

It is used in natural-rubber and synthetic-rubber compounds for conveyor belts, transmission belts and other dynamic technical-rubber goods.

It is used in automotive and industrial rubber hoses, seals, gaskets and vibration-control components.

It is used in rubber masterbatch and compound-manufacturing routes requiring a p-phenylenediamine antiozonant.

It acts as an antiozonant and antioxidant by helping prevent ozone attack, oxidative degradation and flex cracking in dynamic rubber parts.

It has a freezing point around 45 C or higher and density near 1.0 g/cm3.

It is substantially insoluble in water and soluble in common organic solvents.

Confirm assay, melting or solidifying behaviour, ash, moisture, physical form and test method against the compound specification.

Store dry and away from prolonged sunlight in well-closed packaging.

Use suitable PPE when handling and follow the current SDS.
