Ice9 TPU Thermally Conductive and Electrically Non-conducting Pellets 1 kg


Ice9 Flex is a TPU-based thermally conductive composite and the pellets can be used for extrusion, injection molding, and to make filament that is semi-flexible. The material is electrically non-conducting and has a thermal conductivity of 6 W/m-K in the print direction. This material is ideal for heat sinks, heat exchangers, liquid cooling, and the most demanding thermal applications.
