Tuball technology in China

With the aim of meeting the increasing demand of the Chinese composites and flooring industries for highly conductive and reinforced materials, OCSiAl, the Luxembourg-headquartered manufacturer of single wall carbon nanotubes, has entered into a distribution partnership with Chinese raw materials supplier Nanjing Leiqi.

Due to their exceptional characteristics, single wall carbon nanotubes form an interconnecting conductive 3D network throughout a material matrix at extremely low concentrations, starting from just 0.01%. By contrast, to achieve the same conductivity characteristics, multiwall carbon nanotubes require a concentration 10 to 20 times higher, and conductive carbon black requires a concentration 100 times higher.

Nanjing Leiqi will commercialise Tuball Matrix and Tuball Comp_E, concentrates containing Tuball nanotubes.

Tuball Comp_E, based on low-viscosity resins that contain 0.7% of Tuball single wall carbon nanotubes, was developed particularly for providing epoxy and polyester resins with high-level electrical conductivity. The Tuball Matrix line of super-concentrates, which was specially developed for the composites and coatings industries, guarantees uniform volume resistivity in the range OF 108–102 Ω·cm and also increases important characteristics of the material such as strength and fracture and abrasion resistance.

“Chinese manufacturers have always expressed high interest in the most revolutionary technologies and solutions,” said Aleksei Minakov, CEO of OCSiAl China. “The recently held Shanghai International Floor Industry Exhibition has demonstrated once again that the flooring industry sorely needs a universal additive that will enable conductivity of floorings as well as maintain vivid colours and smooth surfaces. Nanjing Leiqi is one of the advanced companies that will make a leap forward in the conductive composites and flooring industries by introducing our single wall carbon nanotubes.”
