​Perpetuus Advanced Materials suggests graphene-based alternative to 6PPD in tires. 

Perpetuus Advanced Materials has introduced an amine functionalized graphene material as a potential replacement for 6PPD (6-para-phenylene-diamine) antioxidants in tires. Using plasma-functionalized graphene nanoplatelets (GNPs), Perpetuus claims the masterbatches can entirely replace 6PPD in rubber formulations, thereby preventing the formation of harmful 6PPDQ by-products.

The masterbatch covers over 90% of the dry-mix ingredients used in tire production, replacing several process oils and additives, improving workplace air quality while keeping mixing simple, said the UK company.
