Saudi Basic Industries Corporation (SABIC), a global diversified chemical company, will appear at the 2023 Shanghai International Electronic Components Exhibition (PCIM Asia 2023). At that time, the company will release a series of new data showing its ELCRES™ HTV150A High temperature dielectric films can significantly reduce internal dielectric losses in potential high temperature capacitor applications.
At temperatures up to 150°C and frequencies of 100kHz, the ELCRES HTV150A The dissipative losses of the film are 40% lower than other high temperature resistant materials such as polyethylene terephthalate (PET) and polyethylene naphthalate (PEN). ELCRES The lower loss of the HTV150A dielectric film helps to reduce internal heating, improve operating efficiency, and stabilize hot spot temperature, thereby giving engineers in the Asia-Pacific region greater flexibility when designing capacitors. Due to the lower dielectric loss of the film, the losses in the capacitor are correspondingly lower.
ELCRES The HTV150A dielectric film is now available to metallization suppliers, capacitor manufacturers and OEMs in the Asia Pacific region. Several local Asian companies are currently evaluating the film in their capacitor products.
Ed Kung, Senior Manager of Resin Design and Incubation at SABIC, said: "During the development of the ELCRES HTV150A film, SABIC Based on their in-depth understanding of the reaction mechanism of polymers under the influence of thermal and electrical stress fields, the researchers selected material components with mild loss mechanisms in the relevant temperature and frequency ranges, and achieved satisfactory results. More and more customers are beginning to design new inverter systems and adopt next-generation silicon carbide power modules, and reducing dielectric loss at higher operating temperatures and frequencies is expected to help customers succeed. "
SABIC will introduce its capacitor film solutions in detail at the exhibitor forum of this exhibition from 13:20 to 13:40 on August 30.
Internal losses are lower than existing materials
SABIC is currently cooperating with Japanese consulting company Machine Technologies Co., Ltd. to jointly develop ELCRES The performance of HTV150A film in the DC bus capacitor of the inverter of the electric vehicle transmission system is researched, tested and verified. This collaboration demonstrates that the ELCRES HTV150A The application value of thin films in supporting technology roadmaps for hybrid electric vehicles, plug-in hybrid electric vehicles and battery electric vehicles (xEV).
Data from recent monolithic thin-film testing at SABIC's Polymer Process R&D Center in Pittsfield, MA, USA shows that ELCRES reacts differently from other high-temperature resistant materials. The HTV150A film exhibits significantly lower internal dielectric losses when exposed to high frequency and high temperature environments. Importantly, these dielectric films from SABIC can withstand temperatures up to 150°C temperature, allowing the DC link capacitors to withstand damaging hot-spot temperatures. The operating temperature of other high-temperature resistant films such as PET and PEN is limited to below 125°C, and the dielectric loss will increase significantly in the environment above 125°C. Furthermore, over the required temperature and frequency range, ELCRES HTV150A film also has excellent dielectric properties retention.
Dr. Tsuyoshi Kasebe, CEO of Machine Technologies, said: "SABIC and Machine Technologies adopts rigorous methods to test and verify capacitor materials, providing customers with detailed data support. Capacitor manufacturers can use this data to understand the performance advantages of ELCRES films compared to other high-temperature materials. This data will be valuable in guiding new capacitor designs as the industry transitions to power transistors based on silicon carbide and other advanced technologies. "
Machine Technologies' specialists have many years of experience in the development and manufacture of capacitors. They are very active in the industry, actively supporting various R&D projects and publishing a series of technical papers.
Superior Performance for Professional Grade Power Capacitors
ELCRES HTV150A Dielectric Film is the first in the industry to operate over a -40°C to 150°C temperature range and up to 100 kHz Under the high frequency, it can still provide products with stable performance, and also has stable capacitance, high insulation resistance and good dielectric properties. Therefore, this material compensates for the traditional polypropylene (PP) film at 105°C The key performance in the above temperature environment is insufficient. Capacitors fabricated with 3-micron and 5-micron metallized ELCRES HTV150A film passed 2,000 Hours of standard electrical and life tests, small changes in capacitance and stable insulation resistance. In addition, the material offers other performance advantages, including high breakdown strength over the entire temperature range, good self-healing properties, and excellent adhesion to aluminum and zinc during metallization.
It has been verified by customers that this film product can be applied to both metal foil electrode and metallized evaporation electrode processes.
