Kapton - Information

[Dino Accoto]

Dear all,

   I would like to deposit a kapton layer on the rectangular aluminium
surfaces of two electrodes, both about 10mm x 5mm. The goal is to
improve the dielectrical strength of the electrodes to avoid sparks when
a voltage of about 7 kV is applied. The electrodes will be sweparated by
air.

Do you any good company I can contact? I would like also to ask them the
dielectric strength and the relative permittivity of the kapton used.

Thanks in advance,
Dino
