Composition with thermal conductivity and laser plating performance by core-shell structure LDS additive with metal compounds coated on mineral filler surface

A thermally conductive polymer composition comprising:

• a. from about 20 wt % to about 80 wt % of at least one polymer component, wherein the polymer component comprises a polycarbonate;
• 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 100 wt %,
• wherein all weight percent values are based on the total weight of the composition,
• wherein a molded sample of the composition has a through plane thermal conductivity of at least about 0.40 W/m·K when determined in accordance with ASTM E1461, and wherein a molded sample of the composition exhibits a notched Izod impact strength of at least 66 J/m when tested in accordance with ASTM D256 at 23° C.
