Graphene nanotubes for thermoplastics

Graphene specialist OCSiAl has launched a new graphene nanotube concentrate for polyamide (PA), filled Polyphenylene sulfide (PPS), Acrylonitrile butadiene styrene (ABS), Thermoplastic polyurethane TPU, and polycarbonate (PC).

The new product provides targeted conductivity in thermoplastics produced by injection molding at working loadings starting from 0.1 wt.% of nanotubes in the final system, the company said.

Painting of exterior automotive parts usually requires separate operation lines for metallic and polymer components, as plastics are insulative. However, this is not necessary when using thermoplastic grades with electrically conductive additives.

“The new product will also be valuable for improving automotive safety and tracking systems,” said Vladimir Kravchenko, development leader at OCSiAl. “We already see demand from manufacturers of fuel system parts including quick connectors, fuel pumps, valves, filter housings, EV-battery caps, and other car components.”
