TUBALL™ graphene nanotubes make it possible to produce conductive silicones without compromising the mechanical properties or color of final compounds, unlike other anti-static agents such as multi wall carbon nanotubes and carbon black.
Thanks to their unique properties, such as high conductivity, strength, and flexibility, graphene nanotubes (or single wall carbon nanotubes) form reinforcing conductive networks inside elastomer materials, even at extremely low working dosages. As a result, by switching to graphene nanotubes as an anti-static agent, compounders can obtain materials with required conductive properties, maintained or even improved mechanical properties and color, without dramatic changes in viscosity or production processes.

To simplify the handling of nanotubes, OCSiAl has developed TUBALL™ MATRIX concentrates that contain high-quality preliminary dispersed graphene nanotubes. Nanotube concentrates allow good dispersion of nanotubes in anti-static silicone with the application of a standard compounding process. Depending on the antistatic agent concentration in the final compound, the processing conditions, and other system components, the volume resistivity can be adjusted within the range of <10 to 1010 Ω·cm.
Graphene nanotubes are widely applied in fields where silicone compounds require electrical conductivity while maintaining their flexibility, such as in electronics and aerospace as cable accessories and connectors, profiles, gaskets, electrodes, and elements of environmental control systems.
TUBALL™ graphene nanotubes provide to LSR, RTV, and HCR silicones:
Currently, OCSiAl offers several varieties of TUBALL™ MATRIX based on different carriers for silicones. Depending on the type of silicone compound, special requirements for resistivity level, and mechanical properties, the appropriate TUBALL™-based concentrate should be used.
