What is polyvinylidene fluoride (PVDF)?

Polyvinylidene fluoride, a semi-crystalline thermoplastic, is produced from the polymerization of vinylidene fluoride. PVDF therefore differs from PE in that around half of the hydrogen atoms have been replaced by fluorine atoms. PVDF is characterized by its very good chemical resistance, especially to chlorine, bromine, acids and hydrolysis. It is relatively hard and impact resistant and is also a good electrical insulator. The application temperature range is comparatively high at – 60 to +150 °C and PVDF is therefore suitable for a wide range of applications, for example in medical technology or mechanical engineering.
