Graphene nanotubes for FRP structures: anti-static properties with maintained mechanical performance
Graphene nanotubes provide pultruded and compression-molded FRP cable trays and gratings with permanent, humidity-independent antistatic performance throughout their service life. Uniform conductivity eliminates insulative spots, making these composites suitable for ATEX/IECEx zones and enhancing overall operational safety.
Effective at very low loadings, graphene nanotubes preserve chemical resistance, durability, and color flexibility. Supplied in ready-to-use forms, they enable clean, dust-free processing and are fully compatible with standard manufacturing equipment and technologies.

Graphene nanotubes for thermoset composites
What can conductive FRP replace steel?
Anti-static fiber-reinforced polymer products are high-performance alternatives to steel for corrosive, demanding, and high-safety environments. Unlike steel, FRP does not corrode, reducing maintenance and extending service life in chemical and industrial applications. Pultruded FRP offers high strength and stiffness for longer spans and reliable load-bearing performance, while compression-molded FRP provides excellent corrosion resistance, design flexibility, and slip-resistant surfaces.
Graphene nanotubes offer better performance
TUBALL™ graphene nanotubes deliver permanent, humidity-independent antistatic performance at very low loadings, preserving mechanical properties and design flexibility. Compared with conventional antistatic additives, graphene nanotubes offer high-performance advantages over:
- migratory liquid additives, which rely on humidity, tend to leach over time, and are unsuitable for long service life or ATEX/IECEx applications;
- carbon black, which provides conductivity only at high loadings, limits color to black, increases weight, and can negatively affect mechanical properties and surface quality;
- metal fillers and fibers, which add conductivity but significantly increase weight, may corrode in aggressive environments, and reduce electrical insulation;

Conductivity with variety of colors
Starting at just 0.01 wt.%, TUBALL™ graphene nanotubes create a stable, three-dimensional conductive network within fiber-reinforced polymers, delivering precise control over electrical resistivity from antistatic to fully conductive. Its ultralow loading preserves the intrinsic properties of the composite and, unlike conventional additives, allows manufacturers to produce durable, high-performance thermoset parts in a wide range of colors.
