Grade: Piezo-electric Film
Formula: PVDF
Form: Foil/Film/Sheet
Material: Polyvinylidene fluoride (PVDF)
CAS Number: 24937-79-9
Commodity: Polymers
Orientation:
Uni-axially Oriented
Piezo-electric PVDF film is a thin piezoelectric polymer film available in 21 variations. This versatile fluoropolymer demonstrates strong piezoelectricity, or the ability to generate an electrical charge in response to applied mechanical stress. With high dielectric strength and chemical inertness, PVDF films are used in acoustic transducers, vibration sensors, hydrophones, and other applications requiring flexible, durable piezoelectric materials. From low-density to metal-coated versions, Goodfellow's selection of piezo PVDF films covers a range of thicknesses, dimensions and properties to suit different industry and research needs.
