Electrical conductivity is a critical factor in the electronics and semiconductor industries, directly influencing device performance, reliability, and miniaturization. As components continue to shrink and circuit density increases, even minor charge accumulation or signal loss can lead to failures, yield loss, or long-term reliability issues.
Graphene nanotubes play a key role in meeting these challenges by providing permanent electrical conductivity at ultralow loadings in various materials. Their stable 3D conductive networks enable precise signal transmission, effective ESD protection, and contamination-free performance, while preserving mechanical properties, color, and processability. As a result, graphene nanotubes support the development of smaller, faster, more reliable, and more versatile electronic and semiconductor technologies.
Graphene nanotubes create permanent, low resistance in materials, enhancing functionality through allowing precise signal transmission and preventing charge buildup to protect ESD-sensitive components and ensure stable, reliable processes.
Robust, conductive 3D nanotube networks, formed at ultralow concentrations, provide durable performance and contamination-free operation while also enabling the clean, vibrant aesthetics essential for consumer wearables and high-precision electronic devices.

Incorporating small amounts of SWCNTs into CB/silica-filled FKM creates a dense filler network that significantly enhances crosslink density, mechanical strength (up to ~90% tensile and ~105% tear improvement), wear resistance, and electrical conductivity, while optimizing properties at low loadings before agglomeration at higher concentrations limits performance.
Incorporating small amounts of CNTs into fluorinated rubber leverages their radical scavenging ability to stabilize thermal degradation processes, dramatically increasing the continuous use temperature from ~200 °C to 340 °C and significantly expanding the material’s high-temperature application range.
Tuball™ products are not only able to overcome the previous difficulties with nanotube dispersion in PU systems, but they are also effective replacements for the ammonium salts and carbon black antistatic agents conventionally used in PU applications.
