Graphene nanotubes provide printing rollers and sleeves with stable, long-lasting anti-static performance, helping maintain ESD-safe operation and low-defect printing. Unlike traditional conductive additives, nanotubes do not migrate or cause surface marking, ensuring clean roller surfaces and consistent print quality.
Nanotube-enhanced rollers and sleeves retain low hardness and high mechanical properties and offer broad design flexibility, including colorability. They are suitable for a wide range of ink types, including solvent-based inks, and perform reliably in flexographic printing on plastic films, cardboard, and paper. Supplied in ready-to-use forms, graphene nanotubes enable clean, dust-free processing and are fully compatible with standard manufacturing equipment and production technologies.
Printing rollers and sleeves often operate at high speeds, where friction between substrates, inks, and machine components rapidly generates static electricity. Even small electrostatic charges can attract dust and ink mist, leading to print defects, streaks, and higher scrap rates. Static buildup can also cause substrate misalignment and unstable web handling, particularly when printing on plastic films or lightweight packaging materials. In environments using solvent-based inks, uncontrolled static may even create spark and ignition risks. Anti-static rollers and sleeves dissipate charge continuously, ensuring stable ink transfer, cleaner surfaces, and safer operation. As a result, they help maintain consistent print quality, higher production efficiency, and reduced scrap rate.
TUBALL™ graphene nanotubes provide an excellent combination of properties for various polymeric materials used in printing rollers and sleeves, including:
Thanks to the unique morphology of graphene nanotubes and the ultralow dosages required—dozens of times lower than conventional anti-static agents—nanotubes enable permanent electrical conductivity while preserving hardness, tensile strength, color flexibility, and non-marking performance.

TUBALL™ graphene nanotubes create a widespread 3D conductive network throughout the material thickness, enabling stable anti-static performance over the entire service life without degradation or insulating “hot spots”. This prevents spark buildup and helps reduce scrap rates.
Tiny working amount of TUBALL™ graphene nanotubes makes it possible to combine electrical conductivity with good aesthetics and broad color possibilities, helping differentiate products on the market.
TUBALL™ MATRIX is a line of concentrates based on polymer carriers and pre-dispersed TUBALL™ graphene nanotubes. They are developed for easy adoption of nanotubes into standard technological process and integration into the original formulation of compounds. It can be diluted into resin using a high-speed mixer, a bead mill, or a three-roll mill, depending on product type.
