By Perpetuus Advanced Materials
Perpetuus has developed an amine functionalised graphene masterbatch that not only prevents the formation of 6PPD-Q, it replaces 6PPD entirely in rubber formulations. Leveraging its proprietary plasma functionalised graphene nanoplatelets (GNPs). “This is no longer about mitigation. We’ve replaced 6PPD.” “Our amine functionalised GNPs deliver the same anti-degradant function as 6PPD, but with zero toxic quinone by-products. This isn’t theory. It works in formulation and scales now.” Perpetuus’ graphene enhanced elastomer masterbatches ship in industrial quantities, supplied in pre-mixed sheets or blocks for direct integration, removing the need for process change and graphene handling. Perpetuus’ GNP based solution achieves rubber protection via a different mechanism: the amine groups on the GNPs act as radical scavengers, stabilising the elastomer and eliminating the need for 6PPD altogether. “This isn't a patch, it’s a permanent replacement.” “By removing 6PPD at the source, we remove the risk of 6PPD-Q entirely.” While 6PPD is most associated with tires, it is also found in a wide range of synthetic rubber products, including hoses, belts, seals, and anti-vibration mounts. These are used extensively in the automotive, construction, and industrial sectors. Perpetuus’ masterbatches are designed to work across all these systems, offering a global path to 6PPD elimination without compromising performance or durability, with price points that enable seamless adoption in commercial supply chains. Production runs on Perpetuus’ continuous plasma platform to deliver repeatable surface chemistry and lot-to-lot consistency. The masterbatch covers over 90% of the dry mix ingredients used in tire production and replaces several process oils and additives, improving workplace air quality while keeping mixing simple.
In parallel, Perpetuus is expanding its product development to include sustainable reinforcing materials such as recovered carbon black (rCB) and Tyre Derived Polymers (TDP), creating a new generation of graphene-enabled circular elastomers. The company is also developing graphene-enhanced synthetic rubber masterbatches to support global manufacturers seeking to reduce their environmental impact while elevating performance.

This clean, solvent free process delivers high quality, surface functionalised graphene nanoplatelets at commercial volumes and competitive costs. At the core of our innovation is a patented DBD plasma treatment process. This technology modifies the surface chemistry of graphene nanoplatelets and other 2D materials, enabling precise functionalisation so they disperse uniformly and bond effectively with host matrices such as rubber, polymers, metals, and composites. Unlike traditional acid or solvent based methods, our plasma process is clean, chemical free, and zero toxic waste. It operates at low temperature and energy input, making it scalable and environmentally responsible. The result is consistent, high quality functionalised graphene, delivered at industrial scale to provide measurable performance gains across every application.

Today, Perpetuus operates globally, supplying industrial quantities of graphene masterbatches and nanomaterials to partners in tyres, elastomers, coatings, fertilisers, metals, and lubricants. This approach shortens R&D cycles, ensures batch-to-batch consistency, and enables the rapid design of graphene masterbatches tailored to customer needs. The result is faster innovation, predictable performance, and scalable solutions for industrial partners.
