Ice9 E-Insulating Nylon Filament

Ice9 Insulating Nylon is a thermally conductive filament that is rigid. The filament is electrically insulating and has a thermal conductivity of 2.5 W/m-K in the print direction. Use this material when you need to remove heat but must maintain electrical isolation or RF transparency. E-insulating Ice9 works best with FDM printers that print flexible filaments.

Electrically insulating and thermally conductive, this materials provides high heat transfer and electrical isolation. This filament is nylon based and has high toughness, enabling good thermal contact for interfacing with heat generating components. The printed parts have an electrical resistivity > 1014 ohm-cm and a breakdown voltage > 5 kV at 1 mm.

TCPoly products are proudly made in the USA.
