POLYONICS XF-300 is a 5 mil (127 µm) nylon film with a permanent pressure-sensitive acrylic adhesive and a high-opacity matte white topcoat, designed for thermal-transfer, dot-matrix or write-on printing. It is dimensionally stable, chemically resistant and rated from −40 to 145 °C, and has been tested in cryogenic laboratory use in liquid nitrogen at −196 °C — making it well suited to wire, cable, terminal and laboratory identification.
