Electrically conductive additive for thermoplastics with retained mechanical performance and required processability

TUBALL™ graphene nanotubes (also known as single wall carbon nanotubes) demonstrate promising results as conductive additives for plastics.

Graphene nanotubes create a dense conductive network inside thermoplastic compounds that guarantees stable electrical conduction performance with no adverse effects on the mechanical and rheological properties of plastics.

OCSiAl markets nanotube-based concentrates for wide range of thermoplastics: glass fiber filled polyamide, polyamide, glass fiber filled PPS, PVC-plastisol, TPU, polycarbonate, ABS, and PC-ABS polypropylene. Other conductive additives with nanotubes for polyethylene, polystyrene, and others are undergoing validation and are referred to as beta products.


Note: This diagram provides average trends compared with other additives based on OCSiAl data. Product performance may vary depending on product type and formulation.

TUBALL™ MATRIX: multiple benefits

  • Enables a new combination of properties in comparison to standard conductive additives 
  • Surface resistivity of 103–109 Ω/sq*
  • Volume resistivity of 103–109 Ω∙cm*
  • Maintains a good balance of mechanical properties
  • Stable performance reducing the number of out-of-spec parts
  • Good processability
  • Permanent homogeneous resistivity without “hot spots”
  • High surface quality
  • Allows production of conductive parts that retain colors
  • Freedom to incorporate other functional ingredients 

*Values may vary depending on the formulation, processing, and products. The values shown are given as the typical reference.

TUBALL™ graphene nanotube solutions for plastics

To adapt nanotubes to a standard manufacturing process without purchasing specific equipment or changing the original formulation, OCSiAl has developed the TUBALL™ MATRIX line of concentrates.
