SARCON® NR-c

Highly Thermally Conductive and Non-Flammable Non-Silicone Gel materials.

Features

SARCON® NR-c is a highly conformable, thermally conductive, non-flammable acrylate resin (non-silicone) sheet with thermally conductive fillers. Available in sheets and die-cut forms for formal interface uses wherever gap filler pads are traditionally used.
