Graphene Ultra Fuel Efficient Tires (GUET)
‘Revolutionizing The Tire Industry’
Gratomic will target mass market sales demand via Graphene Ultra Fuel Efficient Tires (GUET).
In response to market demands, tire manufacturers are seeking to launch ultra-fuel-efficient tires employing graphene-enhanced tread formulations, along with innovative tread pattern designs such as streamlined ribs, blocks, and lugs.
It is widely acknowledged that the pertinent drawback preventing commercialization is the failure of the industry to identify an environmentally friendly large-scale production method to liberate graphenes from the graphite.
Methods currently employed to produce graphenes from graphite, range from mechanical exfoliation (the sticky-tape method) and electro exfoliation, through to “prehistoric methods”, such as “boil graphite in acid”, and chemically or thermally expand it to liberate graphenes. None have been proven to be cost-effective or suitable for industrial scale volume production. With the exception of Gratomic’s collaborative strategic development partner Perpetuus Carbon Technologies (who supply substantial quantity of surface modified graphenes on a monthly basis to the tire industry), current outputs evidently appear to be restricted to R&D and limited quantity proof of concept applications.
Gratomic produces graphenes of a high purity, consistently, and scalability derived from its Graphite Mine in Namibia and its dedicated facility for the patented Perpetuus plasma method.
Ian Walters Director – Perpetuus Carbon Technologies Limited stated:
“Perpetuus’ investigative analysis and characterization have concluded that the Graphenes derived from the Gratomic mine are highly friable, more so than any other graphite tested for
Gratomic IS now on the journey to create the world’s first graphite “vertical” liberating high quality graphenes from its very own graphite for deployment in its own range of tires.
Tires enhanced with graphenes were first produced in about 2014. The global tire market has recognized that employing graphenes within tire treads, walls and the inner linings can make tires lighter, provide better grip and reduce rolling resistance to an extent that is not possible with existing tire compounds. As with all business sectors, from time to time new potentially disruptive innovative developments emerge.
The second iteration of Gratomic graphene-enhanced tread tire compounds
- The use of graphenes in inner liner compounds reduces air permeability.
- Perpetuus is working with tire manufacturers using liberated layers of homogeneously dispersed graphenes for the same purpose.
- The same characteristics have established that varied graphene formulations can be extended to passenger and light truck tire manufacturing.
- The addition of graphenes equals a lighter tire, lower rolling resistance, high impact and tensile properties
- Graphenes offer the potential for a balance of improved economy and superior performance
It should be noted, it is the cycling world that first embraced Graphenes (Vittoria – a bicycle tire specialist). Others eventually took it up in the tire industry, but only for early-stage preproduction evaluation.
So where is the Gratomic enhanced product currently progressing in the global tire industry?
Globally the situation is that currently only several lesser-known tire manufacturers in China have had the vision to pioneer the use of Graphenes in the construction of tires but remain in the R&D phase. Typically, a tire tread compound mix is approximately 205 kilos and will furnish approximately 40 tire treads. Graphenes content is approximately 5 kilos per mix. Graphenes can also be used in the walls and inner lining, but for the sake of this exercise please note these additional volumes are not factored in.
A tire is a complex composite device. There are many ways in which it is possible to improve a single aspect of its performance, such as improving rolling resistance by changing the dimensions of the tire. However, “give and take” variations in compound formulations are inevitably detrimental to other performance parameters. In this sense, the advancement of tire science and technology involves a constant compromise between compatible yet mutually exclusive performance demands.
As a whole, a typical tire is a composite of several parts, primarily sidewalls, inner liner, and the tire tread, which itself is a rubber component. The sidewalls comprise a steel cord and textile reinforced rubber network. If one considers that the tire tread is the only part of the vehicle’s contact with the road, it becomes obviously evident, that the majority of sources of energy dissipation are facilitated by the tread material, which is the prime influencing component on performance, such as handling, fuel efficiency, and braking efficiency.
It is a known fact that adding graphenes changes the shape of the rheology curve, which influences the cure chemistry and results in changes to the rubber compound.
GRATOMIC is a leader in the mining and commercialization of graphite products – specifically the valuable graphene-based nano material that is used for a wide range of mass market elastomer and polymer products, including the US $258 billion* global tire market. We are also aggressively developing other industrial applications such as lubricants, special rust, and proof coatings. Medical and High tech electronic applications.
