Ice9 Nylon Thermally Conductive and Electrically Non-Conducting Filament 1kg


Ice9 Rigid is a nylon based thermally conductive filament with temperature stability above 150°C. The filament is not electrically conductive, yet has a thermal conductivity of 4 W/m-K in the print direction. This filament is ideal for mold tooling, high performance electronics, and any other applications requiring high thermal conductivity, stiffness and temperature stability. Ice9 Rigid works well with most standard FDM printers (with nozzles that can achieve at least 270°C print temperature).
