OCSiAl is the world's largest producer of graphene nanotubes and is the only company with scalable technology for their industrial synthesis. Graphene nanotubes, or single wall carbon nanotubes, are rolled-up graphene sheets. These nanotubes have unique properties – high electrical and thermal conductivity, remarkable strength and high length-to-diameter ratio. When graphene nanotubes are introduced into a material matrix, they create a reinforcing three-dimensional network that also gives the material conductive properties. OCSiAl produces nanotubes under the TUBALL™ brand name. and offers solutions for multiple industries, from Li-ion batteries, thermoplastics, thermosets to elastomers.
The company currently has a 75 tonne annual production capacity, and it plans to increase this up to 175 tonnes with the commissioning of the first train of a new plant in Luxembourg in 2023. Alongside its production apparel, OCSiAl has three R&D centers located in Russia, China and Luxembourg designed to support its clients worldwide.
