TUBALL™ graphene nanotubes (single wall carbon nanotubes) in the form of TUBALL™
MATRIX 814 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:
PVC-plastisols enhanced with TUBALL™ graphene nanotubes have found wide application in the mining, oil & gas, textile, and other industries.
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.
