Perpetuus Advanced Materials has announced the launch of its first nano-engineered graphene-enhanced masterbatch compounds, specifically designed for the commercial, passenger, and industrial tire manufacturing sectors. This initial offering will soon expand to include polymer and elastomer masterbatches for use in industries such as hoses, seals, gaskets, V-belts, and conveyor belts.  

By leveraging its environmentally friendly plasma treatment process, Perpetuus integrates its advanced graphene into the masterbatch. Now available in industrial quantities, this innovation empowers tire manufacturers to seamlessly integrate this groundbreaking material into their existing production workflows.  

The Perpetuus plasma process stands out for its environmental safety, eschewing traditional wet acid, solvent, or surfactant treatments. This eliminates the need for energy-intensive drying stages and the disposal of toxic post-production waste. The dry plasma process significantly reduces energy consumption, aligning perfectly with Perpetuus's commitment to sustainable, large-scale production.  

The graphene masterbatch combines Perpetuus's surface-engineered, plasma-treated graphene with natural rubber, carbon black, and other standard industry fillers, creating an advanced base material for tires and other rubber products.  

Integrating this masterbatch into tire tread formulations delivers remarkable performance enhancements. Road tests have demonstrated up to a 40% reduction in tire tread wear, improved braking, and enhanced handling, particularly in wet conditions. The superior dispersion and bonding of ingredients also minimize PM2.5 tire wear particles, a significant contributor to air pollution, resulting in cleaner air quality.  

John Buckland, CEO of Perpetuus Advanced Materials, stated: "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."  

This innovation aligns with key regulatory initiatives, including the UK's Clean Air Act 2022 and the EU Clean Air Policy, which aim to safeguard citizens' right to clean air. Moreover, reducing tire-derived particles and chemicals in road runoff offers potential benefits for aquatic ecosystems and urban water quality.  

Perpetuus's masterbatch comprises over 90% of the essential 'dry mix' components required for tire production and is delivered in convenient pre-mixed 25 kg blocks. This eliminates the need for plasticizers, process oils, compatibilizers, and resins—many of which are toxic and have been banned in several EU countries. Furthermore, this innovation improves factory air quality by reducing airborne 'fly material', enhancing safety and occupational health.  

Looking ahead, Perpetuus Advanced Materials plans to launch its GRAPHENE C6 range of motorcycle and PCT tires in 2026. Additional graphene masterbatch formulations, including Styrene Butadiene Rubber, will also be introduced for passenger car tires. The flexibility of the masterbatch production process positions it as a sustainable solution for various rubber applications across multiple industries.
