POLYESTER FILM FOR HEAT-RESISTANT CAPACITOR, METALLIZED FILM THEREOF, AND HEAT-RESISTANT FILM CAPACITOR CONTAINING THE SAME |
摘要 |
<p>A polyester film for use in a capacitor having high heat resistance, which consists of a biaxially oriented film containing a polyester (A) as a main component and a polyimide (B) and has a glass transition temperature of 105 DEG C to 145 DEG C and an elongation at break in the machine direction of 70% to 150%, offers a high glass transition temperature and excellent insulation volume resistance and insulation breakdown voltage at high ambient temperatures. This film can produce a metallized film for use in a capacitor having high heat resistance and also a film capacitor having high heat resistance.</p> |
