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.
