PVDF is strong and tough as
reflected by its tensile properties and impact strength.
Compared to many thermoplastics, PVDF has excellent resistance
to creep and fatigue, yet in thin sections such as films, PVDF
components are flexible and transparent.
The following physical property
information is based on typical values of the base Kynar® 740
resin as well as test results obtained from actual film testing.
