Anti-static additive for conductive vinyl ester with maintained durability and color


TUBALL graphene nanotubes (also known as single wall carbon nanotubes) are used as a conductive filler to provide anti-static properties to vinyl-ester systems. They outperform widely used carbon black in their ability to preserve or even enhance mechanical properties of thermoset materials along with providing the required conductivity. Due to ultra-low working dosages in comparison with carbon black or carbon fiber, graphene nanotubes allow a wider color palette, leading to enhanced aesthetics of final products.

Anti-static agents: traditional vs TUBALL™

OCSiAl has developed the TUBALL MATRIX line of user-friendly concentrates for easy handling of nanotubes at a standard production facility without required changes in formulation. The anti-static masterbatch is efficient at very low loadings starting from 0.1% of the overall compound.

Key benefits of graphene nanotubes in vinyl-ester systems include:

  • Uniform conductivity – guaranteed protection from ‘hot spots’
  • Permanent anti-static properties independent of humidity
  • Preserved mechanical properties, or even enhancement of some parameters
  • Flexibility in coloring the product thanks to ultra-low working loading of nanotubes
  • Retained density and viscosity of the original compound
  • Simple adaptation to existing production process and formulation
