Anti-static agent for electrically conductive thermoset resins with maintained mechanical performance and color
TUBALL™ graphene nanotubes (also known as single wall carbon nanotubes) are the most effective anti-static agent. This conductive filler avoids drawbacks in other key parameters, giving thermoset compound manufacturers, engineers and installers the ability to produce highly competitive composites and coatings with a totally new set of properties.
Anti-static agents: traditional vs TUBALL™
Note. This diagram provides average trends compared with other additives based on OCSiAl data. Product performance may vary depending on product type and formulation.
In comparison to conventional ESD additives used for various conductive thermoset resins, such as carbon black, carbon fibers or ammonium salts, TUBALL™ graphene nanotubes deliver the level of conductivity while at the same time preserving the original color of the thermoset compound and maintaining or even improving beneficial mechanical properties.

Graphene nanotube technologies are widely applied in most industries, including the automotive, construction, alternative energy, petrochemical, healthcare, pharmaceutical, electronics, and marine transportation sectors, as well as in cleanrooms and sports equipment.
To adapt nanotubes to a standard manufacturing process without purchasing specific equipment or changing the original formulation, OCSiAl has developed TUBALL™ MATRIX line of concentrates. TUBALL™ MATRIX concentrates are compatible with the most commonly used technologies for the production of fiber reinforced composites, including hand layup, filament winding, pultrusion, SMC/BMC and spray-up.
