BOPP 电容膜粗化膜/BOPP clear rough film for capacitors Features:
Impulse a deep-rough treatment into single side or double sides on the surface of the film in order to form some certain concave ,then let the film be characteristic even roughness ,low dielectric loss, and high dielectric strength and good compatibility with kinds of Dipping Oil but with small Swelling.
Mainly used for Baptist paper composite membrane oil medium or total capacitor dielectric film Baptist Oil: such as high-voltage capacitor and capacitor for electric induction heating system,etc.
