ECTFE Film
ECTFE provides excellent chemical resistance, good electrical properties, a broad-use temperature range from cryogenic to 300°F (150°C), and meets the requirements of UL-94 V-0 vertical flame test in thicknesses as low as 7 mils (0.18 mm). It is a tough material with excellent impact strength and wear resistance.
