Pvdf Film Sensor

  • Polyvinylidene Fluoride (PVDF) Plastic: Material ...

    PVDF (homopolymers and copolymers) is generally synthesized by the free radical polymerization of 1,1-difluoroethylene (CH 2 =CF 2). The polymerization takes place in the suspension or emulsion from 10-150°C and pressure of 10-300 atm. The material obtained is then processed into film or sheets.
