| titleOfInvention | Biaxially oriented polyester film for capacitors |
| abstract | (57) [Summary] [PROBLEMS] To maintain the heat resistance, insulation properties, and possibility of thinning of polyethylene-2,6-naphthalenedicarboxylate, to achieve both workability and space factor, and to significantly improve productivity. The present invention provides a biaxially oriented polyester film for a capacitor. SOLUTION: The polymer component constituting the biaxially oriented film comprises polyethylene-2,6-naphthalenedicarboxylate, and the film has an average particle size of 0.01 μm. 0.03% by weight or more and 3% by weight or less of inert fine particles having a particle size ratio (major axis / minor axis) of 1.0 to 1.2, which is not more than 3.0 μm and less than the film thickness. The number of fly specs having an average diameter of the film surface exceeding 30 μm is 10 / m 2 or less, the variation in the thickness of the film is 25% or less, and the alternating current volume of the film at the time of melting (300 ° C.) The resistivity value is 5 × 10 7 Ω A biaxially oriented polyester film for capacitors, having a thickness of not less than 1 cm and not more than 1 × 10 9 Ωcm. |
