Graphene nanotubes for polyethylene rotomolding: electrical conductivity with preserved mechanical properties and light colors


TUBALL™ graphene nanotubes are applied via easy-to-use TUBALL™ MATRIX, which is a line of additives based on polymer-carriers and pre-dispersed TUBALL™ graphene nanotubes, or TUBALL™ COAT_E suspensions.

TUBALL™ anti-static additive for polyethylene rotomolded parts demonstrates the following benefits:  

  • Low dosage starting from 0.01 wt.% TUBALL™ nanotubes to obtain conductive performance*
  • Permanent, stable, and uniform electrical resistivity without “hot spots”
  • Maintains a good balance of mechanical properties 
  • Possibility of color solutions*
  • Stable performance reducing the number of out-of-spec parts

*Depending on the formulation, processing, and products.

Full range of resistivity: anti-static and conductive

Graphene nanotubes’ unique morphology allows them to create a dense conductive network inside thermoplastic compounds at ultra-low loading rates.
