TWO AXIALLY DRAWN POLYESTER FILM FOR CONDENSER

摘要

PURPOSE: Disclosed is a biaxial oriented polyester film for manufacturing condenser which reduces inferior ratio in manufacturing condenser with excellent insulating property and press property. CONSTITUTION: The biaxial oriented polyester film comprises first polyester film layer having center line average surface roughness of 0.01-0.05μm being deposited with metal layer; second polyester film layer of center line average surface roughness 0.065-0.15μm united on the first polyester film layer. Further, at least one layer selected from the first polyester film layer and the second polyester film layer contains 0.01-2wt.% of inorganic particle having average particle size of 0.001-5μm.
