Polyvinylidene fluoride (PVDF)KF Piezo

A material with limitless possibilities

Kureha was first in the world to successfully develop an industrial manufacturing process for this ferroelectric macromolecular film. Compared to crystal or ferroelectric ceramics, the flexibility of the KF Piezo film provides good workability, allowing wide-ranging use for sensors or speakers.

Characteristics

KF Piezo is made by stretching a KF POLYMER film and applying a high voltage.The molecular structure of the film itself exhibits remarkable piezoelectric and pyroelectric properties.The ability to generate a current in response to pressure, distortion or heat makes this product suitable for a variety of sensors.The KF Piezo film was used on the JAXA solar sail spacecraft IKAROS to detect space dust.

KF Piezo has the following characteristics:

As a macromolecular film, it is thin, light and flexible
Low dielectric constant compared to inorganic piezoelectric bodies makes it suitable for sensors
Acoustic impedance close to that of water makes it suitable for hydrophones and ultrasonic probes
