TUBALL™ is the first graphene nanotube 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 plane rolled in a tube more than 5 µm long. This material is also commonly called single wall carbon nanotubes.
