PVDF
PVDF, polyvinylidene fluoride, is a versatile fluoropolymer which is both strong and tough as reflected by its tensile properties and impact strengths. PVDF has excellent resistances to creep and fatigue. In thin sections, such as films, filament, and tubing, PVDF components are flexible and transparent. PVDF resin is produced by the Arkema and Soltex companies and sold under their respective tradenames of Kynar and Solef.
Where load bearing is important, PVDF fluoropolymers are rigid and resistant to creep under mechanical stress and load. Because PVDF is stable to sunlight, and other sources of ultraviolet radiation, it is widely used as base resins for long-lasting exterior coatings. An additional advantage ov+er other fluoroplastics is that PVDF can be welded into tanks for acid and corrosive chemical processing in elevated temperature environments.
