Product Description
PVDF film with thickness ~7 um, 12 um. 20 um, or 30 um, uniaxially orientated with high dielectric breakdown strength. Dielectric constant about 12 at 25 C and 1 kHz. Only one surface with aluminum electrode (1 ohm/sq)
For R&D and acoustic loudspeaker membrane and electrostatic chuck/brake, electrostatic adhesive, electrostatic energy storage
Only ONE surface with aluminum electrode (about 5 ohm/sq,E-Beam evaporated).
One order is for one sheet with 210 mm x 280 mm. Significant discount for order > 10 m long.
PVDF dielectric constant is about 12 at 25 C adn 100 Hz.
Dielectric breakdown > 400 V/um [small area]
Can generate very high electrostatic force (Maxwell) at lower voltage due to the high dielectric constant.
Large discount for large quantity order.
Aluminum can be etched by dilute KOH, NaOH, or HCl.
Master Roll width 450 mm. > 800 m long.
