THERMALLY CONDUCTIVE AND ELECTRICALLY INSULATIVE POLYMER COMPOSITIONS CONTAINING A THERMALLY INSULATIVE FILLER AND USES THEREOF
摘要:
Disclosed herein are compositions comprising a. from 35 to 80 vol % of a thermoplastic polymer; b. from 5 to 45 vol % of a thermally insulative filler with an intrinsic thermal conductivity less than or equal to 10 W/mK; and c. from 5 to 15 vol % of a thermally conductive filler with an intrinsic thermal conductivity greater than or equal to 50 W/mK, wherein the composition is characterized by: i. a thermal conductivity of at least 1.0 W/mK; ii. a thermal conductivity of at least 7 times the total filler volume fraction times the thermal conductivity of the pure thermoplastic polymer; and iii. a volume resistivity of at least 107 Ohm.cm. Also disclosed are articles and methods of use therefor.
