What OCSiAl Group does
OCSiAl Group is a Luxembourg-headquartered deep-tech materials company and the world's largest industrial producer of single-wall carbon nanotubes (SWCNTs), marketed under the TUBALL brand. Founded in 2010 in Novosibirsk, Russia, by Yuri Koropachinsky and Mikhail Predtechensky, OCSiAl developed a proprietary plasma-based synthesis platform called Graphetron that enables mass production of graphene nanotubes at prices reportedly 75 times lower than nearest competitors. The core product, TUBALL, is a universal additive used at ultra-low loadings (0.01-0.2%) to deliver permanent conductivity, mechanical reinforcement, and improved cycle life to host materials, spanning batteries, elastomers, thermoplastics, thermosets, coatings, and composites.
The company's product portfolio extends beyond raw nanotubes to application-ready concentrates and dispersions, including TUBALL MATRIX (super-concentrates for resin systems), TUBALL COMP_E and COMP_O (concentrates for epoxy/polyester systems), TUBALL BATT and FOIL (Li-ion battery dispersions and nanotube-coated foils), and TUBALL COAT (conductive coatings). Manufacturing spans the original Novosibirsk Graphetron facility (4 tonnes/year, expandable), a Serbia production plant opened in September 2024 (60-120 tonnes/year capacity plus a 200-tonne concentrate line), and a planned $300 million Differdange, Luxembourg flagship targeted for 2028-2030 to reach up to 1,000 tonnes/year.
OCSiAl generates revenue through direct SWCNT and concentrate sales, licensing and technology transfer for partner-produced suspensions, and collaborative manufacturing arrangements. Distribution is via a 20-distributor network covering 50+ countries, supplemented by Sigma Aldrich catalog sales, regional offices (Seoul, Hong Kong, Shenzhen, Tel Aviv, Columbus), and a direct online store. The company serves 1,500+ customers globally, including LG Energy Solution, ProLogium (gigafactory supply), LANXESS, BüFA Composite Systems, Duksan, BAK Power Battery, Shanghai Aleees, and ZCT. Revenue is not publicly disclosed; the company was valued at approximately $2 billion in its 2021 funding round, which raised over $100 million with RUSNANO and Daikin Industries as investors.
