Saudi Basic Industries Corporation (SABIC), the world’s leading diversified chemical company, has introduced two new ULTEMTM UTF120 polyetherimide (PEI) capacitor film products for professional temperature-resistant capacitors. A new addition to the industry-leading family of ULTEM UTF120 film products, the 7 micron and 10 micron film thickness grades have responded to the market demand for films that meet different capacitor voltage standards while offering more possibilities for innovative designs. SABIC’s ULTEM UTF120 thin film technology offers significant advantages in capacitor applications, including high dielectric constant, high dielectric resistance and low dielectric loss. Two new film thickness grades address the need for higher film thickness and higher charge storage in high voltage applications. The new grade of ULTEM UTF120 film on the market is attributed to a portfolio of SABIC’s continued expansion, including the 5 micron ULTEM UTF120 film product introduced last year. Currently, SABIC is the only material supplier that offers a choice of such PEI extruded film thicknesses.
“Today, power electronics applications require better product performance and higher reliability than ever before,” said Stephanie Gathman, Director of SABIC’s Emerging Applications Group. “SABIC has been actively investing in the development of innovative high temperature film technology to provide products that are superior to traditional solutions, such as higher thermal resistance, better electrical stability and longer life. With the introduction of two new ULTEM UTF120 films, we will continue to advance our product portfolio expansion strategy to provide better performance support for a full range of values for capacitor voltage and energy density.”
Unique capacitor solution
SABIC’s 7 micron and 10 micron ULTEM UTF120 capacitive film products enable thin film capacitors to be lightweight, compact, and high energy density designs, and can store large amounts of electrical energy for long-term reliable operation, avoiding current leakage even in high temperature environments Or charge loss. This technology provides key features such as high dielectric constant, high insulation resistance and low dielectric loss for capacitor applications, and maintains stable performance even at high operating temperatures or high frequency ranges of 150 °C.
ULTEMUT120 film has unmatched low resistance compared to conventional capacitor film materials such as polypropylene (PP) and polyethylene terephthalate (PET) in the temperature range of -40 ° C to 150 ° C / high temperature performance. Therefore, SABIC film products can be used in harsh working environments such as electric vehicle DC/DC converters and electric compressors. Because ULTEM UTF120 film is suitable for high temperature working environments, it can reduce or even completely solve the need for active cooling of the capacitor used in the main converter through the secondary power supply. For example, PP and PET film capacitors typically require a cooling cycle system for cooling, and this film product minimizes the need for a cooling cycle system. In conventional products, the use of a cooling circulation system can occupy a large space under the bonnet and imposes certain restrictions on design flexibility.
Capacitors with ULTEM UTF120 film can be used in reflow soldering processes up to 260 ° C (industry standard operating temperature). In addition, SABIC film products can provide excellent metallurgical evaporation, capacitor winding and leveling (pressing) operations. This product can be processed on existing equipment and its operational feasibility has been proven in film/foil and metal electrode applications, covering a wide range of metal electrode designs, including flatness, taper and patterning.
SABIC will continue to expand the ULTEM UTF120 film portfolio. Currently, all products in this product family are available for the global market.
