About

About OCSiAl OCSiAl is the world’s largest manufacturer of graphene nanotubes, also known as single wall carbon nanotubes, and the only company with scalable industrial production. Its high-purity nanotubes, branded TUBALL™, provide permanent, ESD-compliant conductivity and enhanced mechanical properties in elastomers at ultralow dosages, without compromising color, surface quality, tensile properties, or elastic performance. To simplify integration, OCSiAl offers TUBALL™-based concentrates and dispersions for rubbers, silicones, and latex, used in a wide range of applications—from tires and sensors to cables and textiles. Headquartered in Luxembourg, the company operates globally and partners with over 1,500 companies across 50+ countries. OCSiAl is the world’s largest manufacturer of single wall carbon nanotubes (SWCNTs), owning the only scalable technology capable of synthesizing them in industrial volumes. SWCNTs—nature’s longest and most flexible material for conductivity and reinforcement of electrodes, including high-performance cathodes, thick electrodes, silicon anodes, or semi-solid batteries. Benefits of SWCNTs in electrodes result in a reduced dosage of conductive additives compared to MWCNTs and carbon black, and significantly higher energy density. OCSiAl produces high-purity sSWCNTs under the brand name TUBALL™. TUBALL™ BATT, an ultrafine dispersion of SWCNTs in liquid carriers, is a ready-to-use solution designed for high-energy anodes and cathodes, enhancing the energy density and durability of batteries.
