TUBALL™

Graphene nanotubes

TUBALL™ IS A GAME-CHANGING MATERIAL

TUBALL™ is the first graphene nanotubes to be available for the commercial application of this novel material in a wide range of industries.

Graphene nanotubes can be described as a one-atom-thick graphene sheet shaped as a tube more than 5 µm long. This material is also commonly called single wall carbon nanotubes. TUBALL™ has potential applications across up to 50% of global materials markets.

How it works

When embedded into a material’s matrix, well-dispersed TUBALL™ graphene nanotubes create a 3D reinforced and conductive network that provides a new set of properties and has minimal impact on the other key properties of final product.

UNIQUE PROPERTIES OF GRAPHENE NANOTUBES

Graphene nanotubes are carbon nanomaterials with breakthrough properties that can significantly enhance the physical properties of other materials.

    Graphene nanotubes give advantages unachievable with other additives and make it possible to create revolutionary products and materials. TUBALL™ nanotubes have the potential to transform other materials in unprecedented ways and provide significant benefits across a broad range of end uses.
    For some specific applications, ultrapure TUBALL™ could be recommended.

    NANOAUGMENTED MATERIALS AND THE FUTURE OF VARIOUS INDUSTRIES

    Graphene nanotubes allow us to create materials which were previously impossible and products that will change many industry standards and the look of the present-day world. This new generation of materials is called nanoaugmented materials.

    As one example, graphene nanotubes accelerate next-generation e-mobility upgrades. Nanotubes give the possibility of a lighter car body, leading to a decrease in the dead load of the vehicle; an altered tread and sidewall composition of tires that can reduce rolling resistance; nanotube-reinforced plastic car components that can replace metal parts; and next-generation EV batteries with graphene nanotubes leveraging the achievement of higher energy density, faster charging, a longer lifetime, improved safety, and lower . These improvements open the door for a reduction of up to 25% in car weight and up to 30% improvement of its energy efficiency.
