SABIC to highlight at PCIM Asia 2025 specialty dielectric films that address challenges of high-voltage, high-heat electrical applications

• At PCIM Asia 2025, SABIC will give a talk on ELCRES^™ HTV150 dielectric film and will also present voltage derating test results for Nichicon capacitors that use this ultra-thin film.
• High-voltage capacitors made with ELCRES HTV150 film can operate at high temperatures up to 150°C with minimal derating.

SABIC, a global leader in the chemical industry, will showcase at PCIM Asia 2025, in Hall N5, Booth F03, ultra-thin ELCRES^™ HTV150 dielectric film that is well suited for capacitors used in demanding electrical applications, including AC-DC inverters in electric vehicles (EVs). Advanced capacitors made with the SABIC film can operate at high temperatures up to 150°C with minimal derating of applied voltage (V). This capability will be discussed in two technical presentations during the event.

“Higher voltages are a common theme across electrical applications, from connectors and capacitors to wire and cable,” said Sergi Monros, vice president, SABIC Polymers, Specialties BU. “While high voltages can increase operational efficiency, they present challenges. SABIC continues to lead and innovate in this space. Our specialty materials perform well under exposure to high voltages, high temperatures and harsh conditions, helping customers deliver next-generation electrified components.”

Minimizing Voltage Derating in Film Capacitors

Exposure to elevated temperatures can significantly lower the rated voltage of polymer film capacitors. For example, the rated voltage for capacitors made with biaxially oriented polypropylene (BOPP) film may be reduced by up to 50 percent at 125°C and above, requiring thicker gauges to compensate. However, recent testing by Nichicon, a leading Japanese capacitor manufacturer, showed that capacitors made with SABIC’s ELCRES HTV150 dielectric film experienced minimal derating (4.8 percent at 130°C and 14 percent at 150°C).

SABIC Chief Scientist Adel Bastawros, Ph.D., will speak on these voltage derating test results from Nichicon from 11:40 a.m. to 12:00 p.m. China Standard Time (CST) on Thursday, Sept. 25, 2025, in the E-Mobility session. His presentation is titled “HTV150 Dielectric Film for High Heat DC-Link Capacitors with Minimal Derating of Operating Voltage.”

Dr. Bastawros will also give a talk titled “Voltage Derating Behavior of High Temperature Capacitors for DC-Link Applications.” This presentation is scheduled for Friday, Sept. 26, 2025, at 12:15 p.m., at the Technical Conference.

Solutions for Diverse Electrical Applications

In addition to ELCRES HTV 150 dielectric film, SABIC supplies ULTEM^™ and NORYL^™ resins and LNP^™ copolymers and compounds with a high comparative tracking index (CTI). This property is important in situations where electrical components are exposed to harsh environments or contaminants and high voltages.

PCIM Asia will take place in Shanghai, China, Sept. 24-26, 2025.
