Product Description
PVDF film with thickness 7.0 um or 12 um. Uniaxially Oriented with one surface with aluminum electrode (30 nm)
For R&D and acoustic loudspeaker membrane and electrostatic chuck/brake, electrostatic energy storeage
Only ONE surfaces with aluminium electrode (about 1-10 ohm/sq,E-Beam evaporated).
One order is for one sheet with 210 mm x 280 mm.
PVDF dielectric constant is about 12 at 25 C adn 100 Hz.
Dielectric breakdown > 400 V/um
Young's modulus is >2.2 GPa
Can generate very high electrostatic force (Maxwell) at lower voltage due to the high dielectric constant.
Large discount for large quantity order.
Aluminium can be etched by dilute KOH, NaOH, or HCl.
Master Roll width 400 mm. > 1000 m long.
