EP2 Enhanced Polyimide is a filled product with copper adhesion superior to traditional polyimides. Is said to reduces water absorption,
(by 25%) increase thermal conductivity and reduce CTE while maintaining the full 250°C Tg of polyimide for thermal stability through process and application. Reduces cure cycle by 25 - 50%. Z-axis expansion is 0.65% at 50° to 260°C, copper peel is 25% higher than traditional unfilled polyimides, and Td (5%) is 424°C compared to traditional polyimides. Meets IPC-4101/40 and 41. Non-MDA chemistry resists drill fracturing. Is compatible with lead-free solder processing. Meets NASA outgassing and UL-V0 flammability requirements. Is RoHS and WEEE compliant.
