BOPET CAPACITOR FILM

It is used for film-capacitor (and other electrical insulation material.) which features dielectric strength, dielectric constant and volume resistance, low dielectric loss, good mechanical performance and dimension stability.

Thickness :3-12 UM

Width : 500,620,670 MM

Net weight per roll about : 50KGS/roll

Inner plastic tube core : 3”,6” (76MM ,152MM )

By the way , we also manufacture the BOPET metalized (VM/--Zn /Al ) capacitor film.
