Does blended film improve the high-temperature resistance of capacitor films?
The high-temperature breakdown strength and charge/discharge properties of the blended film are significantly improved compared with that of pure BOPP film. In recent decades, enhancing the high-temperature resistance of capacitor films was a research focus, but largescale-producing high-temperature resistant films remains a difficult issue.
