Papers for capacitors
As a base paper we use a special grade of paper in thicknesses from 8 bis 12 µm with specific gravities of 1.17 to 1.3 g / cm³.
This film can be metallized either with pure aluminum (99.98 %), zinc or zinc-aluminum alloy.
The electric resistance (metallization strength) and the kind of metallization will be according to the customer's requirements.
Here are our standard kinds of metallization available:
One side metallization with single side margin right / left
One side metallization with heavy edge type BLEND and single side margin right / left
Double side metallization over entire area (no margin)
Double side metallization with coincidental margin
Double side metallization with heavy edge type BLEND and coincidental margin
Double side metallization with diagonal margin
Other designs like double or multiple internal series, step and tapered metallizations and many others on request.
