Graphene nanotubes
TUBALL™ GRAPHENE NANOTUBES UNIVERSAL ADDITIVE
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 of the examples, they bring forward the electric transportation of the future. Car parts from nanoaugmented composites would be as strong as those made of steel but much lighter and smarter. Light nanoaugmented tires with increased wet grip and enhanced abrasion resistance will reduce the energy costs of the car, while conventional cars waste up to 30% of their energy on dissipation in tires. New Li-ion batteries based on graphene nanotubes are vastly superior to existing Li-ion batteries in terms of power, energy storage and cycle life. This provides a strong impetus to the development of e-mobility and alternative energy.
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.
