SABIC has introduced its new 5-micron ELCRES HTV150 dielectric film for high-temperature, high-voltage, professional-grade capacitor applications, such as traction inverters for hybrid, plug-in hybrid and battery electric vehicles (xEV).

This new film, featuring high-heat performance up to 150°C, surpasses the temperature and voltage capabilities of incumbent products. It can help support the transition from conventional semiconductors based on silicon (Si) to next-generation, wide-band-gap technologies based on silicon carbide (SiC), improving the efficiency of inverter modules.

“Our new ELCRES dielectric film allows customers to leverage silicon carbide’s increased power capability while operating at temperatures up to 150°C. This innovative film can support significantly improved inverter module operation to help drive higher performance in xEV and other demanding applications,” said Scott Fisher, business director, ULTEM products and Additives, SABIC.

New ELCRES HTV150 dielectric film can support the design of high-voltage, high-temperature DC link power capacitors that can store large amounts of electrical energy for long periods without significant leakage of current or loss of charge.

This technology offers potential advantages for capacitor applications, including very good dielectric and insulative properties, as well as low loss at the high frequencies and high temperatures at which wide-band-gap semiconductors operate.

The new ELCRES HTV150 film offers high reliability that is important for next-generation xEV. Based on internal testing, the film demonstrated a lifespan of 2,000 hours at 500V and 150°C. Furthermore, it is self-healing in the event of a breakdown caused by excessive voltage.

This combination of high voltage stability at high temperatures, low dielectric loss at high frequency and ability to self-heal to avoid catastrophic failure differentiates ELCRES HTV150 film from traditional capacitor films.

With an operating temperature range of -40°C to 150°C and high voltage performance, ELCRES HTV150 dielectric film is suitable for demanding applications, such as power capacitors for the latest EV traction inverters and onboard chargers. The film can also be used for power capacitors in mass transportation, renewable energy, aerospace and motor drives and controls.

SABIC’s ELCRES HTV150 dielectric film can be used in industry-standard metallization, capacitor winding and flattening processes. It has been validated on existing equipment and with various metallized electrodes, including flat and tapered metallized designs as well as patterned electrodes.

SABIC is currently collaborating with Shin-Etsu Polymer Co., Ltd., a leading Japanese company that specializes in ultra-thin film extrusion, to produce ELCRES HTV150 film.

“Combining SABIC’s innovation in high-heat materials and our expertise in ultra-thin film extrusion, our joint effort will deliver a long sought-after solution for industries seeking high-performance, high-voltage capacitor technology,” stated Yoshiaki Ono, President of Shin-Etsu Polymer.

“Our deep expertise in material science, combined with our commitment to understand global megatrends and downstream customer requirements and develop associated capabilities such as electrical testing, has enabled us to deliver this unique solution to the industry,” added Greg Stoddard, technical director, Resins and New Chemistries, SABIC.
