A grade similar in composition and properties to G-10 but more suitable for continued use at elevated temperature. G-11 retains at least 50% of its structural strength at elevated temperatures in excess of 300°F. Due to its higher cost, G-11 applications are limited to only the most critical high heat situations.
G-11: Mil-I-24768/3, Type GEB
Typical applications include higher heat or structural applications that G-10 or FR-4 can't meet.
