In the following report the change of elongation, stress at break and other properties of various
fluoropolymers exposed to high concentrations of pure solutions of chlorine dioxide (ClO2) at temperatures
between 20 and 25°C are discussed. The coupons were tested in two groups, one group for 9 months and the
other for 15.5 months. As expected, most of the fluoropolymers have shown only small changes of their
properties.
