Graphene nanotubes for polyurethane cast systems and coatings: permanent electrical conductivity with preserved mechanical properties


TUBALL™ graphene nanotubes, also known as single wall carbon nanotubes, provide permanent electrical conductivity to polyurethanes while preserving mechanical properties.

TUBALL™ graphene nanotubes are applied via easy-to-use anti-static masterbatches:

Other benefits provided by TUBALL™ nanotubes for thermoset polyurethanes:

  • Low dosage gives greater flexibility in the final formulation
  • Easy to apply and the low dosage makes the logistics less complex and more efficient
  • Wide range of colors for various conductive PU coating and textile applications

TUBALL™ graphene nanotubes are applied via easy-to-use TUBALL™-based products.
