TUBALL™ graphene nanotubes in the form of TUBALL™ MATRIX 821 beta and TUBALL™ MATRIX 808 are versatile conductive additive that has been specifically designed to provide superior electrical conductivity to thermoplastic materials, while retaining mechanical properties and providing acceptable injectability to 30–50 wt.% glass fiber filled PPS compounds.

Benefits provided by TUBALL™ nanotubes for GF-filled PPS: 

• Low dosage starting from 0.1 wt.% TUBALL™ graphene nanotubes* to obtain conductive performance
• Enables a new combination of GF filled PPS properties in comparison to standard conductive agents 
• Maintains good balance of mechanical properties
• Keeps MFI level at acceptable range for 30–50 wt.% glass fiber filled compounds
• Permanent, stable, and homogeneous electrical resistivity without “hot spots”
• Stable performance reducing the number of out-of-spec parts
• Good processability and easy handling

*Dosages may vary depending on the formulation, processing, and products.

CONDUCTIVITY, PROCESSABILITY, MECHANICAL PERFORMANCE

Graphene nanotubes’ unique morphology allows them to create a dense conductive network inside thermoplastic compounds at low loading rates—starting from 0.1 wt.% in the total compound.

The usage of TUBALL™ MATRIX preserves key mechanical properties and provides acceptable injectability.

Case: 2 wt.% TUBALL™ MATRIX 821 beta (0.2 wt.% TUBALL™ nanotubes) in 30 wt.% glass fiber filled PPS

*OCSiAl internal study. Results may vary depending on the formulation, processing, and products.
