Abstract:
1. A composition comprising: a. from 35 to 80 vol % of a thermoplastic polymer comprising an aliphatic polyamide, polyester, polyethylene and ethylene based copolymer, polypropylene, polyphenylene sulfide, polyetheretherketone, polycarbonate, or polyetherimide, or a combination thereof; b. from 5 to 45 vol % of a thermally insulative filler with an intrinsic thermal conductivity less than or equal to 10 W/mK comprising H c. from 5 to 15 vol % of a thermally conductive filler with an intrinsic thermal conductivity greater than or equal to 50 W/mK comprising AlN, BN, MgSiN wherein the composition is characterized by: ii. a thermal conductivity of at least 7 times the total filler volume fraction times the thermal conductivity of the pure thermoplastic polymer; and
