Abstract
The disclosure concerns thermally conductive polymer compositions comprising: (a) from about 20 wt % to about 80 wt % of at least one polymer component; (b) from greater than about 0 wt % to about 70 wt % of a thermally conductive filler; and (c) from about 0.1 wt % to about 40 wt % of a laser activatable additive having a core-shell structure; wherein the core comprises an inorganic filler and the shell comprises a laser activatable component; wherein the combined weight percent value of all components does not exceed about 100 wt %; wherein all weight percent values are based on the total weight of the composition; and wherein a molded sample of the blended thermoplastic composition has a through plane thermal conductivity of at least about 0.40 W/m·K when determined in accordance with ASTM E1461.
