PEI Film - T 0.05mm 300mm x 300mm

Details

SKU: 1000073207 Product Code: EI31-FM-000150
PEI Film delivers high thermal endurance, dielectric performance, and dimensional stability, making it ideal for precision electrical insulation, optical substrates, and thermal barriers in demanding environments. Resistant to hydrolysis and many solvents, it performs reliably in aerospace, automotive, and electronics industries. Applications include flexible printed circuits, capacitor dielectrics, and transparent thermal shields. Specific uses range from flexible connectors in avionics to moisture-resistant dielectric layers in battery systems and optical interlayers in high-temperature glazing. In research, PEI film is used to explore thin-film polymer optics, high-temperature dielectric behavior, and fabrication of microelectronic substrates. Its combination of clarity, stability, and heat resistance ensures it remains a preferred choice for advanced engineering and scientific applications.
