Product Description

Uniaxially oriented PVDF homopolymer film with thickness 18 um. High dielectric constant >12, High Dielectric Breakdown Strength > 600 MV/m. Great for high energy density film capacitors and piezo film

The uniaxial orientation significantly improved the dielectric breakdown strength (energy density) and reduced the leakage current and energy loss.

This film is NOT poled and it is non-piezoelectric. But the customer can pole the film by themselves.

This listing is for small rolls of 18 um thick film with 360 mm wide, three different length. On 3" ID paper core.

25m/50m/100m length
