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:
Other designs like double or multiple internal series, step and tapered metallizations and many others on request.
|PAPL||Plain-Paper (non Metallized)|
|PAMAD||Aluminum Metallized double side|
|PAMAR||Aluminum Metallized with Heavy Edge|
|PAMRD||Aluminum Metallized double side with Heavy Edge|
|PAMZR||Zinc Metallized with Zinc Heavy Edge|
|Nominal thickness (μm)||8.0 / 9.0 / 10.0 / 12.0|
|Slitting width||≥ 8.0 mm|
|Free margin||≥ 1.5 mm|
|Inside core diameter||75 mm|
|Roll outside diameter||155 mm / 165 mm / 180 mm / 200 mm / 240 mm / 330 mm|
|Typical properties||high temperature resistance. low dissipation factor at high temperatures. high dielectric constant – and with that high capacity with small capacitor volume|
