Polyvinylidene fluoride plastic

Polyvinylidene fluoride plastic is a polymer material with some very interesting piezoelectric properties. Polyvinylidene fluoride plastic has found widespread uses in the ultrasound industry, due primarily to its flexibility, and the fact that its acoustic impedance is so much lower than piezoelectric ceramics. It is relatively lossy compared to ceramics, has relatively low electromechanical coupling and a lossy dielectric constant that decreases with frequency, but in spite of all this Polyvinylidene fluoride plastic remains firmly rooted in the industry as a material of choice for a number of applications.

Polyvinylidene fluoride plastic properties

The electromechanical coupling of polyvinylidene fluoride plastic is lower than that of piezoceramic, but since the foil thickness can be as little as 10 micrometres the vibration mass is extremely small. Polyvinylidene fluoride plastic also has greater damping than ceramics, and the resulting dynamic characteristics allow very short pulses to be generated. This means that it is possible to measure shorter ranges using polyvinylidene fluoride plastic than is possible with piezoceramic transducers.

Polyvinylidene fluoride plastic applications

Polyvinylidene fluoride plastic is suitable for manufacture and lining of equipment used in aggressive environments where a high degree of mechanical and thermal resistance is required. Polyvinylidene fluoride plastic in injection: thin-walled parts and parts in highly complex shapes, valve seats; Polyvinylidene fluoride plastic in extrusion: antistatic parts, films, sheets and plates; Polyvinylidene fluoride plastic in blowing: films and hollow parts
