PVDF (Polyvinylidene fluoride) is a fluorinated thermoplastic resin which has outstanding resistance to most mineral and organic acids, aliphatic and aromatic hydrocarbons, alcohols, halogenated solvents, and oxidizing environments. It also has outstanding aging resistance, with its properties remaining constant after many years. PVDF also has remarkable fire resistant properties. In the Underwriters' test, PVDF was given the highest classification (V-O), indicating that it was non-flammable and self-extinguishing. PVDF will also provide UV and gamma radiation stability and very high dielectric and piezoelectric constants. PVDF is FDA compliant, absolutely non-toxic and can be used in repeated contact with food products. Its surface, like glass, is unfavorable to the proliferation of microorganisms. Good mechanical properties in tension as well as in deflection, torsion, and compression compared to other fluorinated polymers and will not swell or alter in a wet environment.
