Clean-room gloves classified as ISO Class 4–8 must be anti-static to prevent electrostatic discharge (ESD), which can damage sensitive electronics or disrupt production. Graphene nanotubes are the only material currently available on the market that provides a permanent, humidity-independent anti-static effect in nitrile gloves while requiring only minimal changes to the manufacturing process. The resulting electrical conductivity not only ensures reliable ESD protection in compliance with clean-room glove standards (IEC 61340-4-9 and ANSI STM11.11) but also enables seamless touch-screen use without removing the gloves and wide color variety.
Clean-room gloves are essential for contamination control and ESD protection, primarily in electronics, semiconductors, aerospace, and pharma. They protect both workers and sensitive products. Anti-static gloves are engineered to safely dissipate static electricity from workers’ hands, protecting sensitive equipment and processes in such environments as electronics manufacturing or pharmaceutical production sites. To ensure effective ESD protection, they must meet strict volume resistivity requirements—below 10⁵–10¹¹ Ω—in compliance with the IEC 61340-4-9 / ANSI STM11.11 standards as well as preserving other vital properties such as particle generation, low outgassing, clean-room classification, and chemical resistance.
Ultra-long, flexible, and electrically conductive, graphene nanotubes create a robust 3D network within materials at ultralow concentrations of just 0.05–0.1 wt.%. They offer a stable alternative to traditional polymer or salt-based coatings, which can be prone to degradation. Thanks to their unique properties, graphene nanotubes enhance durability and ESD protection while preserving the material’s original color and softness. As a result, they outperform conventional conductive additives across all key performance parameters.

As industrial automation advances, ESD safety standards are becoming stricter. The IEC 61340-4-9 / ANSI STM11.11 and EN 16350 standards for gloves raised the bar, limiting the use of many traditional anti-static additives. Graphene nanotubes rise to the challenge, delivering permanent, humidity-independent conductivity that fully complies with the latest standards in ESD protection as well as providing required performance to clean-room gloves suitable for electronics, semiconductors, EV batteries, and many more applications classified as ISO Class 4–8.
