TPL specializes in fabrication of high‐quality thin films for capacitors. Physical deposition or casting of polymer film is performed on ultra‐smooth release substrates in a class 100 clean room. Continuous film fabrication can be achieved to a thickness of 3.0 μm with a narrow distribution.
Controlled solvent removal and/or thermal curing is achieved with multiple radiant and convection oven zones. Product film rolls can then be processed using conventional film roll winding and processing.
TPL’s unique film production capabilities is being combined with advanced material technology to develop high performance capacitors. Wound film capacitors are currently being developed for high temperature and pulsed power applications.
