Anti-static additive for conductive polyester with maintained durability and color
TUBALL™ graphene nanotubes are a universal conductive agent that outperforms its analogues, such as carbon black, carbon fiber, mica or other conductive polymers, in the stability of conductive properties and the wide color palette it unlocks for end products.
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.
For simple adoption of nanotubes in a standard manufacturing process with original equipment and formulation, OCSiAl has developed a line of user-friendly TUBALL™ MATRIX concentrates. The effective loading of this conductive filler in overall polyester compound is about 0.5%, which is a dozen times lower than that of carbon black.
TUBALL™ MATRIX anti-static masterbatch in polyester systems enables:
- Permanent, stable conductivity without ‘hot spots’
- Flexibility in coloring of final product
- Simple handling without the powder or dust associated with other carbon nanomaterials
- Possibility to apply via spraying techniques thanks to no viscosity increase
