We are a professional manufacturer specializing in fluoropolymer materials and tubing products.
The high-performance PVDF piezoelectric film is manufactured from modified PVDF resin through melt extrusion and specialized polarization treatment, achieving d33 >26 pC/N. With a maximum width of 1600 mm and customizable length, the film combines chemical resistance, flexibility, and multifunctional electrical properties, making it ideal for military, medical, industrial, and consumer electronics applications.
Product Description
The PVDF Piezoelectric Film is produced from modified PVDF via melt extrusion and subsequent special polarization treatment. This process achieves a high piezoelectric constant (d33 >26 pC/N), enabling sensitive performance in flexible film form.
Thanks to the unique processing, the film can be produced in continuous rolls up to 1600 mm width, and cut to desired length and size depending on application. In addition to its piezoelectric, dielectric, and pyroelectric properties, the film exhibits excellent chemical resistance, high-temperature performance, UV/weather resistance, oxidation stability, and radiation resistance.
