Reinventing composites

Louise Smyth

While targeting uniform and permanent conductivity in composites, graphene nanotubes enable significantly reduced loads of conductive additive, which helps to cut costs and boost technical and operational gains.   

OCSiAl – a high-tech company with a unique, patented technology for mass producing graphene nanotubes – will introduce improved material properties, including efficiency and performance, permanent conductivity, and industrial colors, for composite materials at booth # 9/C41 at Composites Europe on November 6–8 in Stuttgart. OCSiAl will display its off-the-shelf innovative technology, TUBALL™ MATRIX, which is a line of super-concentrates specially developed for simplifying nanotube handling. A loading of just 0.1% of this concentrate is sufficient to provide materials with resistivity values in the range of 108–102 Ω·cm, while reinforcing the structure and maintaining the original color. The line of concentrates is developed for application in most common industrial formulations.

Conductive and durable conveyor belts, anti-static and enhanced urethane and silicone industrial rollers, reinforced composite rebar, fiberglass storage tanks with homogeneous anti-static properties, industrial PU shoes and cleaning pigs with improved diagnostic accuracy – it’s only a part of a solid track record performed by manufacturers advancing their competitiveness with TUBALL™ graphene nanotubes.  

OCSiAl was the first, and is so far the only company, to be authorised to undertake large-volume commercial shipments and marketing of single wall carbon nanotubes in Europe, North America and other key markets. TUBALL™ graphene nanotubes are the first single wall carbon nanotubes to be registered in accordance with the EU’s REACH (Registration, Evaluation, Authorisation and Restriction of Chemicals) regulations: in September 2016, TUBALL™ nanotubes were registered under the number 01-2120130006-75-0000. OCSiAl has also submitted its PMN file to the US Environmental Protection Agency (EPA) and has received PMN submission number P-17-0257.
