It has been reported that with polyethylene terephthalate (PET) and polyethylene naphthalate (PEN)
Compared with other heat-resistant materials such as SABIC’s HTV150A film based on Elcres polycarbonate copolymer, it can withstand 150 ° C and up to 100
At a frequency of kHz, the dissipation loss can be reduced by 40%. The material has already demonstrated its capabilities in thin-walled capacitor films.

The low dissipative losses of the HTV150A dielectric film can reduce internal heating, improve operating efficiency and stabilize hot-spot temperatures, giving engineers greater flexibility in designing capacitors. Lower losses in these films are expected to translate into lower dissipative losses in capacitors.
Ed Kung, Senior Manager, SABIC Resin Design and Incubation Division, said: “In the development of Elcres
When developing the HTV150A film, SABIC researchers drew on their deep understanding of how polymers respond to thermal and electrical stress fields. They selected material compositions with mild dissipation mechanisms in the temperature and frequency ranges of interest and achieved impressive results. As customers design new inverter systems and adopt next-generation SiC power modules, reduced dissipative losses at higher operating temperatures and frequencies help drive success. ”
The performance of the film has been tested
SABIC is working with Japanese consultancy Machine Technologies to research, test and validate Elcres
Performance of HTV150A thin films in electric vehicle (EV) powertrain inverter DC link power capacitors. This ongoing collaboration confirms that Elcres
The value of HTV150A films in supporting hybrid, plug-in hybrid and battery electric vehicle (xEV) technologies.
New data from tests on monolithic films at SABIC’s Polymer Processing Development Center in Pittsfield, Massachusetts, show that Elcres
The HTV150A film exhibits significantly reduced internal dissipation losses when exposed to high frequency and high temperature. Importantly, these SABIC dielectric films can operate at temperatures up to 150°C, enabling DC-link power capacitors to withstand damaging hot-spot temperatures. Competitive high-temperature films, such as PET and PEN, are limited to operating temperatures below 125°C because of their increased heat loss above that temperature. Elcres
HTV150A film also maintains dielectric properties over the required temperature and frequency range.
Dr. Tsuyoshi Kasebe, CEO of Machine Technologies, said: “SABIC and Machine
Technologies provides collaborative support to customers by applying rigorous methodologies to test and validate capacitor materials. The data generated through this process can allow capacitor manufacturers to understand the capabilities of Elcres films compared to other high heat materials. This data could be valuable in guiding new capacitor designs as the industry transitions to power transistors based on silicon carbide and other advanced technologies. ”
High performance over a wide temperature range
Elcres
The HTV150A dielectric film is the first in the industry to provide stable performance at operating temperatures from -40°C to 150°C and at frequencies up to 100kHz, while providing stable capacitance, high insulation resistance, and good dielectric properties . They address a critical performance gap experienced by traditional polypropylene (PP) films above 105°C.
Metalized Elcres with 3µm and 5µm
Capacitors made of HTV150A film pass 2000 hours of standard electrical and life tests at 150°C with small capacitance changes and stable insulation resistance. Other key properties cited by SABIC include high breakdown strength over temperature, good self-healing, and excellent adhesion to aluminum and zinc during metallization. The film has been validated by customers for use in thin film foils and metallized electrodes.
