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.
The following physical property
information is based on typical values of the base Halar® 300
resin as well as test results obtained from actual film testing.
