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.
✔ 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)
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
