Sabic expands portfolio of Ultem film for dielectric capacitors




Sabic is introducing two new gauges of Ultem UTF120 polyetherimide (PEI) dielectric film for high-temperature, professional-grade capacitor applications. These new additions of 7µm and 10µm (micron) thicknesses to Sabic’s industry-leading portfolio of Ultem UTF120 film respond to customers’ requirements for film that can meet the voltage requirements of different capacitors and open the door for new design options.
Sabic’s Ultem UTF120 film technology offers important advantages for capacitor applications, such as high dielectric constant and insulation resistance and low dielectric loss. The two new grades address the need for higher-voltage applications that require thicker film with greater storage capacity. These new Ultem UTF120 film grades are part of an expanding portfolio that already features a 5µm Ultem UTF120 film product, which was launched last year. Today, Sabic is the only materials supplier offering extruded PEI film at these thicknesses.
“Today’s power electronics applications demand higher performance and greater reliability than ever before. Sabic is actively investing in new high-temperature film technologies that offer distinct advantages over previous options, including better thermal and electrical stability and longer service life. With the introduction of these two new Ultem UTF120 film grades, we are continuing to deliver on our strategy of building a broad portfolio that can support a full range of capacitor voltages and energy densities,” said Stephanie Gathman, director, emerging applications, Sabic.
