UK fleets could save over £300m annually with graphene-enhanced truck tyres, says Levidian
Levidian Nanosystems has presented a prototype truck tyre made with a butadiene rubber tread compound containing its net zero graphene, and reports that this compound “has been shown to deliver significant improvements in the mechanical and dynamic properties of the tyre.” The Cambridge-based firm is confident such tyres can deliver considerable fuel and CO2 savings.
No free-standing nanotubes released in tyre tread wear – OCSiAl
A tyre with a tread enhanced with single wall carbon nanotubes was exposed to accelerated wear and handling simulation tests by Akron Rubber Development Laboratory. Analysis of captured airborne particles showed no free-standing nanotubes, according to Luxembourg-based OCSiAl, which produces carbon nanotubes.
Vittoria invests 10 million euros in Italy Cycling Innovation Centre
VittoriaVittoria, the bicycle tyre brand famous for using graphene in its compounds, has invested 10 million euros in quadrupling its Brembate (Bergamo, Northern Italy) premises from 10,000 to 40,000 square metres. The expansion project will see the company add a Cycling Innovation Centre and Bike Park.
Recycled tyres + graphene = SpaceMat
SpaceMatAs we have all witnessed during the last 12 months, the recycled tyre business is experiencing something of a renaissance at the moment. And the abilities of wondering molecule graphene are well-documented. But what happened when you combine the two? The answer, according to one Greater Manchester-based startup is SpaceMat.
Versarien wins £1.95 million graphene research development agreement
Versarien plc, which makes nanocompounds for tyre applications amongst other things, is was awarded a product development funding from the Defence, Science and Technology Laboratory (DSTL), a part of the Ministry of Defence at the end of November 2020.
Versarien appoints chief technology officer
Versarien plc, the AIM-listed the advanced materials engineering group, announced on 7 January that it has appointed Dr Stephen Hodge as the company’s Chief Technology Officer (CTO). Dr Hodge joined the company’s board with immediate effect.
Graphene-enhanced tyre test results “a breakthrough in tyre technology”
Gratomic Inc., a Canadian company focused on the mine to market commercialisation of graphite products, reports positive results from extensive testing of its graphene-enhanced tyres. It views these results as a “breakthrough in tyre technology that warrants deployment into the global tyre market.”
Linglong’s graphene tyre research audited
Research on graphene rubber composites, conducted by Linglong Tire and Beijing University of Chemical Technology has been audited by the Beijing Municipal Science & Technology Commission, according to the tyre company.
Gratomic and Perpetuus partner in graphene tyre project
Canada-based Gratomic Inc. has signed a letter of collaboration with Perpetuus Carbon Technologies Limited to develop and market graphite-derived graphenes and graphene hybrids for tyre elastomers. According Gratomic, a number of end-user customers (which in this case means tyre manufacturers) are already road-testing tyres based on this material. Bicycle tyres, motorbike tyres, military tyres and race tyres are said to be key areas of interest.
Directa Plus collaboration: graphene to boost Marangoni retreading performance
The performance of Marangoni retreading products is expected to benefit from a new strategic collaboration between Marangoni and Directa Plus plc, a leading producer and supplier of graphene-based products for use in consumer and industrial markets. Under the terms of the agreement, both Marangoni and Directa plus will work together to develop a bespoke version of the Directa’s Graphene Plus (G+) for use in Marangoni truck and bus tyre retreading compounds.
European tyre maker trialling Versarien’s Nanene
A small beginning, but a beginning nonetheless: Advanced engineering materials group Versarien plc announced today that a “leading tyre producer, based in Europe” has placed a purchase order for its proprietary Nanene few layer graphene nano-platelets. This order was cultivated via Versarien’s distributor OQEMA plc, formerly Lansdowne Chemicals Limited.
Directa Plus awarded patent for G+ elastomeric composition for tyres

Graphene – the tyre filler of the future?
Initial data suggests graphene tyres offer 1.5x better rolling resistance and better mileage, braking 2016 has been the year that graphene has been most clearly and most publically associated with tyres. And with initial reports suggesting this material could have a dramatic effect on rolling resistance (and therefore emissions) as well as treadwear, it seems […]
