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.
More than 70% of all basic materials can be improved by introducing a universal additive, graphene nanotubes. Graphene nanotubes can be described as a one-atom-thick graphene sheet rolled in a tube more than 5 µm long. This material is also commonly called single wall carbon nanotubes.

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.
OCSiAl is the only company to have created a technology permitting the production of nanotubes for large-scale commercial applications. The OCSiAl’s invention of breakthrough yet low-cost mass-production technology for TUBALL™ with unlimited scalability has made its widespread use economically viable while preserving its high quality. The company's technology is protected with patents and patent applications in >40 countries.
OCSiAl is currently the world’s largest manufacturer of graphene nanotubes.
OCSiAl’s R&D Centers in Luxembourg, Russia and China are continually developing new products with graphene nanotubes and technologies that simplify their use, along with delivering technical support to company’s partners.
