A new film for high temperature film capacitors
Polyolefin Blends are the solution
Applications like renewable energy sources and electro-mobility create a fast growing market for inverter circuits for power conversion – an important component in these applications are film capacitors. Depending on an effective heat management and miniaturization there is a demand for film dielectrics with an increased temperature stability. In order to fulfil the required temperature stability (≥ 125°C), Brückner started in a cooperation with the raw material supplier Topas Advanced Polymers to test polyolefin blends based on polypropylene and cyclic olefins (PP/COC blend).
