Abstract:
1. A composition comprising liquid crystalline polymer, in an amount between about 15 and about 75 weight percent of the composition; thermally conductive filler having a thermal conductivity of at least 5 W/mK, in an amount between about 25 and about 85 weight percent of the composition, wherein said thermally conductive filler is at least one selected from the group consisting of calcium fluoride, magnesium oxide, magnesium carbonate, boehmite and zinc sulfide, wherein the thermally conductive filler has an average particle size between 1 micron and 100 microns; and at least one fibrous filler having a thermal conductivity of at most 5 W/mK, in an amount between about 5 and about 30 weight percent of the composition, wherein the fibrous filler comprises wollastonite, glass fibers, glass flakes, aluminum borate fibers, calcium carbonate fibers, or potassium titanate fibers, further wherein said composition has a volume resistivity that is larger than 1×10 10 ohm·cm.
