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.
