    GL General-Type Polyimide Yellow Film – Biaxially Stretched Standard PI Film For Flexible Insulation


    Product Overview


    Our GL General-Type Polyimide Yellow Film is a biaxially stretched, naturally amber-colored polyimide film designed for high-temperature insulation, adhesive tapes, and flexible circuit coverlays. Available in two optimized thicknesses (25μm & 50μm), it balances mechanical strength, thermal stability, and electrical properties—making it a versatile choice for electronics, aerospace, and industrial applications.


    Key Features


    ✔ Biaxial Orientation – Uniform MD/TD strength (3:1 stretch ratio)
    ✔ Thermal Class H (180°C continuous)– Withstands soldering and reflow
    ✔ Natural Yellow Hue (No dyes) – UV-resistant, no color migration
    ✔ High Dielectric Strength– Reliable insulation for thin layers
    ✔ Adhesion-Ready Surface – Corona-treated (50-52 dynes/cm)


    Applications

    • FPC Coverlays – Flexible circuit insulation

    • High-Temp Tapes – Masking, splicing, and EMI shielding

    • Motor/Transformer Insulation – Anode current collectors

    • Heater Elements – Backing for flexible heaters

    • Printed Electronics – Substrate for conductive inks
