POLYONICS XF-782 is a 2 mil (50 µm) polyimide film with a low-charging acrylic pressure-sensitive adhesive, a high-opacity semi-gloss white static-dissipative topcoat and a low-charging liner, designed for thermal-transfer printing. Its surface resistance sits in the static-dissipative range (10⁸–10¹¹ Ω) and it stays stable through reflow and wave-solder — for safe identification of static-sensitive assemblies.
