Title:
POLYESTER FILM AND ELECTRICAL INSULATION SHEET MANUFACTURED USING SAME, WIND POWER GENERATOR, AND ADHESIVE TAPE
Document Type and Number:
WIPO Patent Application WO/2016/139992
Kind Code:
A1
Abstract:
A polyester film provided with a layer (a P layer) that contains a crystalline polyester (A) and also contains plate-like particles (b1) each having an aspect ratio of 2 or more and/or needle-like particles (b2) each having an aspect ratio of 2 or more, wherein the Young's modulus of the polyester film is 2 GPa or more and the values Wb and V/Wb are 10 or more and 1 or less, respectively, wherein Wb (% by mass) represents the total content of the plate-like particles (b1) each having an aspect ratio of 2 or more and the needle-like particles (b2) each having an aspect ratio of 2 or more in the P layer, and V (% by volume) represents the porosity in the P layer.
Provided is a polyester film having excellent electrical insulation properties, heat conductivity and mechanical properties. Using the polyester film, there are provided: an electrical insulation sheet and an adhesive tape each having high and excellent heat conductivity; and a wind power generator, an electronic device and the like each manufactured using the electrical insulation sheet or the adhesive tape.
