Conductive Polyvinyl Chloride: ESD Аgent for Color & Durability

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:

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.
