Anti-static agent for conductive PVC-plastisol compounds with good mechanical performance and possibility for coloring

TUBALL™ graphene nanotubes (single wall carbon nanotubes) in the form of TUBALL™
 concentrate are an industry-friendly form of anti-static additive for PVC plastisol formulations. They have been specifically designed to provide superior electrical conductivity to thermoplastic materials while retaining the mechanical properties of PVC plastisol.

TUBALL™ MATRIX 814 anti-static additive for PVC plastisol demonstrates the following benefits:

  • Stable, permanent conductivity
  • Preserved original color of compound
  • Retained or even improved mechanical performance
  • Versatile application technologies
  • Clean production without the dust usually associated with carbon black
  • Flexibility in compound formulation thanks to a low dosage of nanotubes
  • User-friendly form of concentrate with no additional equipment required

PVC-plastisols enhanced with TUBALL™ graphene nanotubes have found wide application in the mining, oil & gas, textile, and other industries.

Graphene nanotubes vs carbon black & ammonium salts

In contrast to ammonium salts and carbon black, graphene nanotubes enable a full set of properties: stable,permanent conductivity with preserved original colors and mechanical performance. This is possible thanks to graphene nanotubes’ unique morphology, which allows them to create a dense conductive network inside thermoplastic compounds at ultralow loading rates—starting from just
0.01 wt.% in the total compound.
