TUBALL™ graphene nanotubes (SWCNT) are a conductive filler with the best price-per-property performance in comparison with standard ESD additives, such as conductive carbon black, mica, carbon fibers and conductive polymers. Its ultra-low effective loading (starting from only 0.1% in the form of concentrate in the overall compound) is enough to create a uniform conductive and reinforcing network without a negative impact on the other key properties of a thermoset resin.
Note. This diagram provides average trends compared with other additives based on OCSiAl data. Product performance may vary depending on product type and formulation.
As even and homogeneous dispersion is key to achieving the desired properties, OCSiAl has developed TUBALL™ MATRIX – a line of concentrates that makes it easier to apply nanotubes in a standard manufacturing process and to adapt existing formulations.
TUBALL™ MATRIX anti-static masterbatch in phenolic systems offers the following benefits:
|Parameter||Ammonium compounds||Carbon black||TUBALL™ MATRIX|
|Working dosage, wt.%||0.2–4||4–12||0.1–0.5|
|Resistivity range, Ω/sq||108–1011||105–1011||104–1011|
Influence on mechanical performance
|small negative||strong negative||none|
|Influence on rheology||none||strong negative||acceptable|
|Application via spray technology||possible||challenging||possible|
|Dust formation during production||none||high||none|
|Resistivity independent of humidity||no||yes||yes|
|Stable resistivity over time||no||yes||yes|
