Conductive additive for glass fiber filled polyamide compounds with maintained mechanical properties and required processability
TUBALL™ graphene nanotubes in the form of TUBALL MATRIX 821 beta and TUBALL MATRIX 808 are a 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 PA:
- 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 a good balance of mechanical properties
- Keeps the MFI level within an 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 use 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.
