Anti-static additive for conductive phenolic resin with maintained durability and color

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. 

Anti-static agents: traditional vs TUBALL™

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:

  • Guaranteed uniform, permanent conductivity
  • Preserved or even improved mechanical performance
  • Maintained original color of the compound
  • Minimal effect on density and viscosity
  • Easy adoption thanks to user-friendly concentrate form
