​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… Read More »​Perpetuus Advanced Materials suggests graphene-based alternative to 6PPD in tires.
