Perpetuus Advanced Materials

UK-based Perpetuus Advanced Materials has reported a reduction in operating temperature using low loadings of plasma treated, surface engineered graphene nanoplatelets (SE-GNPs) homogeneously dispersed into a standard propylene glycol water cooling fluid.

In a series of controlled laboratory experiments, the addition of 0.1% SE-GNPs (functionalized with oxygen groups) to a 25% propylene glycol, 75% water solution produced a consistent temperature reduction of approximately 6°C compared with the base fluid alone. The results were repeatable across multiple test runs. The experiments were conducted in a static test configuration designed to isolate material behavior and confirm result consistency. Further validation under forced flow conditions and application specific cooling geometries is currently underway.

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.

The masterbatch covers over 90% of the dry-mix ingredients used in tire production, replacing several process oils and additives, improving workplace air quality while keeping mixing simple, said the UK company.

According to reports, Perpetuus Advanced Materials, following the successful launch of its sustainable graphene-enhanced natural rubber masterbatch, had announced a joint venture with Asiatic Rubber.

This partnership marks a milestone in the commercial deployment of its advanced elastomer technologies across India and Asia. The new venture includes a comprehensive upgrade of Asiatic’s existing manufacturing facility to produce graphene, natural rubber carbon black masterbatch. This material is currently under evaluation by several of India’s leading multinational tire producers.

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

By utilizing its environmentally friendly plasma treatment process, Perpetuus incorporates its advanced graphene into the masterbatch. This innovation is now available in industrial quantities, enabling tire manufacturers to integrate this breakthrough material into their existing production workflows.

A recent announcement was made by Perpetuus, stating that following 18 months of close collaboration between Perpetuus and Vittoria scientists, development work along with extensive laboratory to terrain testing has been completed on the first commercial elastomer to contain hybrid graphene fillers for the tire industry.

According to the statement, a new standard for nano surface engineered graphenes for cycle tires has now been established. This next generation graphene technology reportedly enables Vittoria to produce tires that are superior to all others within the cycle tire market.

UK-based Perpetuus Advanced Materials announced the completion of a "real world" road testing program of car tires enhanced with surface-engineered graphene materials.

Over the last 6 months, Perpetuus graphene enhanced tires were fitted to high mileage, commercial light vehicles, which primarily travel on the UK’s A and B roads. The tests compared the graphene-enhanced tires with regular tires and monitored the performance of both tires. Perpetuus says that the tests showed that the graphene-enhanced tires produced an average of 40% increase in wear resistance over the regular tires.

Gratomic, formerly called CKR Carbon Corporation, recently announced that it is expecting to commercialize graphene-enhanced tires in 2018 as a result of its advanced R&D program to include plasma-generated graphene in tires to increase their strength and reduce their.

Gratomic’s graphene material is reportedly being tested in pre-production trials by 5 major tire manufacturers in Asia and Europe with a consolidated demand in excess of 5000 tonnes of graphene annually.

The UK-based Perpetuus Advanced Materials announced an exclusive commercial agreement with Heraeus, a leading international precious metals and technology group, headquartered in Germany.

As part of this collaboration, Heraeus has completed quality control and customer feedback exercises based on Perpetuus nano carbon, low temperature, high conductivity, functionalized graphene-based inks. Along with Perpetuus, Heraeus will now launch the new range of high quality, cost effective pastes. Production is set to commence immediately.
