TUBALL™ graphene nanotubes in the forms of TUBALL™ MATRIX 800-x series are high-performance and cost-efficient conductive agents for glass fiber filled polyamide compounds. It has been specifically designed to provide superior electrical conductivity to thermoplastic materials, while retaining mechanical properties and minimally impacting the host matrix.

Full range of resistivity

Graphene nanotubes unique morphology allows them to create a dense conductive network inside thermoplastic compounds at ultra-low loading rates – starting from just 0.05 wt.% in the total compound.

30% glass fiber filled polyamide compounds. Injection molded samples. Surface resistivity: ASTM D257. Volume resistivity: ASTM D4496.

Maintained mechanical properties

The usage of TUBALL™ MATRIX preserved key mechanical properties in comparison to other conductive additives.

30% glass fiber filled polyamide compounds. Injection molded samples. ISO 527, ISO 178, ISO 179.

Easy-to-apply with standard equipment

TUBALL™ MATRIX can be processed with standard equipment widely used in the thermoplastics industry. Recommended approach to produce conductive GF PA compound. Other final processing methods can be applied.

Benefits provided by TUBALL™ nanotubes for GF filled PA:

• Ultra-low dosage starting from just 0.05 wt.% of TUBALL™ graphene nanotubes*
• Maintains good balance of mechanical properties
• Provides thermoplastic compounders with opportunity for new conductive products development
• Permanent, stable and homogenous electrical resistivity without “hot spots”
• Stable performance reducing the number of out of spec parts
• Good processability
• Allows production of conductive parts that retain colors

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

PA enhanced with TUBALL™ graphene nanotubes have found wide usage in the automotive e-painting, automotive safety and ESD and ATEX applications.
