2026/07/14 230°C High-Heat-Resistant Epoxy Encapsulation Material Expands Applications for SiC Power Modules Japan’s Sumitomo Bakelite has developed a solid epoxy resin encapsulation material, the EME-G785 series, for next-generation silicon carbide(SiC)power modules, and has officially begun mass production. This material achieves an industry-first high glass transition temperature(Tg)of 230°C, meeting the stringent requirements for power semiconductor encapsulation materials used in high-temperature operating environments. Although SiC semiconductors can operate at temperatures above 200°C, the encapsulation materials used to protect semiconductor components still face challenges in heat resistance, making this a key issue in the development of next-generation power modules.
