Conductive High Temperature Nylon

Abstract

Increasing the thermal and electrical conductivity of typically insulating polymers, such as nylons, would open new markets. A thermally conductive resin could be used for heat sink applications. An electrically conductive resin could be used in static dissipative and Electromagnetic Interference/Radio Frequency Interference shielding applications. This research focused on adding conductive fillers (namely carbon black and Thermocarb, a high quality synthetic milled graphite) and a chopped glass fiber to high temperature nylon. These materials were extruded and injection molded into test specimens. Tensile tests as well as in-plane electrical resistivity, in-plane thermal conductivity, and through-plane thermal conductivity tests were conducted.
