Perpetuus Advanced Materials has revealed its first graphene-enhanced masterbatch compounds, tailored for the commercial, passenger, and industrial tyre sectors. The product range will expand to include masterbatches for elastomer applications, such as gaskets, conveyor belts, hoses, seals, and V-belts.
Using its proprietary plasma treatment process, Perpetuus incorporates advanced graphenes into a masterbatch that is now available in industrial quantities. This development allows tyre manufacturers to easily adopt the material into their production processes.
The plasma treatment process is environmentally friendly, avoiding the traditional wet acid and solvent techniques that produce toxic waste and require energy-intensive drying. This dry process conserves energy and reflects Perpetuus’s commitment to sustainable production methods.
The graphene masterbatch combines plasma-treated graphenes with natural rubber, carbon black, and industry-standard fillers. Its inclusion in tyre tread formulations results in significant performance improvements, such as a 40% reduction in tyre tread wear, improved wet braking, and enhanced handling. The masterbatch also reduces PM2.5 tyre wear particles, helping combat air pollution caused by road abrasion.
John Buckland, CEO of Perpetuus Advanced Materials, said: “In the 20 years since graphene was discovered, almost every use for the material has been developed in laboratories around the world, however the lack of affordable high quality graphenes has prevented known commercial applications coming to market. Our plasma treated surface engineered graphenes solve this problem which are now available in commercial quantities to all sectors of industry.”
The masterbatch supports regulatory initiatives like the UK’s Clean Air Act 2022 and the EU Clean Air Policy. It also offers potential benefits for aquatic ecosystems and urban drainage systems by reducing the tyre-derived pollutants that enter waterways.
Pre-mixed in 25 kg blocks, the masterbatch contains over 90% of the core dry mix components used in tyre production. By eliminating toxic additives such as plasticisers, process oils, and resins, it improves factory air quality and worker safety, while enhancing the efficiency of tyre production.
Perpetuus plans to expand its product line further in 2026 with the introduction of its GRAPHENE C6 motorcycle and PCT tyres, as well as additional masterbatch formulations, including Styrene Butadiene Rubber for passenger vehicles. The scalable production process enables sustainable innovation across multiple rubber industries.
