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.
