  • Thermosetting polymer formulations, circuit materials, and methods of use thereof
    Patent number: 10123412
    Abstract: A thermosetting polymer formulation includes: 40 to 90 volume percent of a thermosetting polymer system; 10 to 40 volume percent, preferably 20 to 35 volume percent, preferably 20 to 30 volume percent, of a plurality of hexagonal boron nitride platelets having a mean particle diameter of 5 to 20 micrometers, preferably 8 to 15 micrometers, and a D10 particle diameter of 3 to 7 micrometers, preferably 3 to 5 micrometers, and a D90 particle diameter of 20 to 30 micrometers, preferably 25 to 30 micrometers; a total of 0.01 to 10 volume percent of a coupling agent, an impact modifier, a curing agent, a defoamer, a colorant, a thickening agent, a release agent, an accelerator, or a combination comprising at least one of the foregoing, wherein the volume percentages are based on the total volume of the formulation.
