Metal polyester film
Metal polyester film
◆ Characteristic
The metal film is deposited on the surface of the film by vapor deposition of aluminum or zinc aluminum in a vacuum state. The material has high dielectric constant, high insulation resistance, good heat resistance, good tensile property, and is suitable for the production of a metal polyester film capacitor.
