POLYONICS XF-101G is a 1 mil (25 µm) polyimide film with a high-temperature permanent acrylic pressure-sensitive adhesive and a high-opacity high-gloss white topcoat engineered for thermal-transfer printing. It stays dimensionally stable and legible through reflow, wave-solder and aqueous cleaning — a workhorse label for PCB and electronics traceability.
