What’s PVDF Piezoelectric film?
PVDF flexible piezoelectric film, or polyvinylidene fluoride piezoelectric film, is a new type of polymer piezoelectric material. It is soft, light, and highly flexible. It has the characteristics of both fluororesin and general resin. In addition to having good chemical resistance In addition to corrosion resistance, high-temperature resistance, oxidation resistance, weather resistance, and radiation resistance, it also has special properties such as piezoelectricity, dielectric properties, and pyroelectric properties. It is currently the second-largest production volume of fluorine-containing plastics. product. PVDF flexible piezoelectric film combined with microelectronics technology can be made into a variety of high-performance sensors such as piezoelectric, ultrasound, and touch. It can be made into components of various shapes and thicknesses as required.
