Is 6PPD the same as Antioxidant 4020?

6PPD is commonly marketed as Antioxidant 4020 in the rubber industry. Confirm CAS 793-24-8, physical form and the agreed batch specification, because commercial naming and packaging can differ.

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

No. 6PPD-quinone is an oxidation transformation product with a different chemical identity from 6PPD. It should not be treated as a synonym or substitute in a rubber compound.

Product Introduction

6PPD (CAS 793-24-8), N-(1,3-dimethylbutyl)-N′-phenyl-p-phenylenediamine, is supplied as a p-phenylenediamine rubber antidegradant. We offer it for approved tire and technical-rubber compound formulations that specify 6PPD as an antioxidant and antiozonant. Every offer identifies the chemical as 6PPD itself, not its oxidation product 6PPD-quinone.

Applications

Pneumatic tire compounds, including selected tread, sidewall and carcass-related systems.
Natural-rubber and synthetic-rubber compounds for conveyor belts, transmission belts and other dynamic technical-rubber goods.
Automotive and industrial rubber hoses, seals, gaskets and vibration-control components where 6PPD is specified.
Rubber masterbatch and compound-manufacturing routes requiring a p-phenylenediamine antiozonant.

Grade and Supply Details

We confirm the required assay, melting or solidifying behaviour, ash, moisture, physical form and stated test method against the approved compound specification. Commercial 6PPD is normally offered as violet-brown pellets, pastilles or granules in 25 kg laminated bags and palletized bulk arrangements. A batch COA, with the applicable TDS and SDS, is available for the offered material.
