SABIC, a global leader in the chemical industry, will introduce at PCIM Europe 2022, in Hall 7, booth 142, a new, thinner gauge of its ELCRES™ HTV150A dielectric film which may be used for capacitors in the traction inverters, onboard chargers and electrical compressors of hybrid, plug-in hybrid and battery electric vehicles (xEV). The 3-micron (µm) film is 40 percent thinner than SABIC’s recently announced 5 µm film, enabling further volume and weight reductions and greater design flexibility through enhanced energy density for the capacitor. Like the 5 µm ELCRES HTV150A film, this exceptionally thin film maintains stable performance at high operating temperatures up to 150°C and addresses the critical performance gap experienced by traditional polypropylene (PP) films above 135°C. This new level of thermal performance helps customers to increase the adoption of SiC power modules with smaller package size due to the higher energy density, reducing weight while providing greater efficiency and performance desired for increased xEV adoption by consumers.
SABIC’s participation at PCIM Europe will include a poster presentation and an e-mobility seminar, titled “ELCRES™ HTV150A Film – New Generation Capacitor Films for 150°C High Voltage AC-DC Inverter Applications.” Dr. Adel Bastawros, chief scientist, Technology & Innovation, will speak at both events. The poster presentation will be held on May 11 at 3:05-5:00pm Central European Time (CET) in the Foyer ground floor, NCC Mitte. The e-mobility seminar will take place on May 12 from 2:50-3:10pm CET in Hall 6, booth 6-224. At its booth, the company will exhibit ELCRES HTV150A film and typical capacitor applications.
“When we launched the five-micron ELCRES HTV150A film last year, we committed to develop thinner gauges to meet requirements for different capacitor voltages – and we’ve delivered on that pledge,” said Greg Stoddard, technical director, Resins and New Chemistries, SABIC. “Our new three-micron film can help customers design smaller package sizes that potentially avoid the use of active cooling systems associated with films that perform at lower temperatures. As OEMs design electric and hybrid vehicles to operate at specific voltages, the new three-micron film can help with differentiation by providing tailored properties. Segmentation of voltage performance aids automakers to match capacitor performance to the needs of different vehicles in their product lines.”
HIGHER TEMPERATURES, THINNER GAUGES
ELCRES HTV150A dielectric film is the first capacitor film in the industry to be engineered for stable performance at operating temperatures of -40°C to 150°C and frequencies up to 100 kHz, while offering stable capacitance, high insulation resistance and good dielectric performance (dielectric constant (Dk) of 2.9, dissipation factor (Df) of 0.0017). Other key properties include high breakdown strength over the full temperature range, good self-healing and excellent adhesion to aluminum and zinc. The film has been validated by customers for use with both film-foil and metalized electrodes. Capacitors built with 3 µm and 5 µm metalized films pass standard electrical and life tests at 150°C for 2,000 hours with low capacitance change and stable insulation resistance. Additional key features and benefits, typical properties and potential applications for SABIC’s ELCRES HTV150A film portfolio can be found in SABIC’s new brochure.
SABIC will continue to develop new products to meet higher heat requirements as inverter technology advances, demonstrating its strong commitment to deliver innovative material and film technologies to the power electronics industry.
PCIM Europe 2022 will run from May 10-12, 2022, in Nuremberg, Germany, on the Messe Nuremberg event grounds.
