Capacitors

The leading supplier for capacitor film lines

Expertise in both, sequential and simultaneous stretching process

Polypropylene (PP) and polyethylene terephthalate (PET) are the preferred choice of raw material for capacitor film. The dielectric strength of both is increased considerably by biaxial orientation, inducing a more perfect crystalline formation. Since 1970, when the first capacitor line supplied was by Brückner, more than 40 lines have been successfully installed.

Brückner's vast experience in the sequential and simultaneous stretching process guarantees the highest film quality down to 0.5 µm thickness and production speeds from 300 – 350 mpm and an output of up to 1,100kg/h. It goes without saying, that the whole line is 100 % clean room suitable.
