PVDF (polyvinylidene difluoride) is a highly non-reactive and pure thermoplastic fluoropolymer. It is produced by the polymerization of vinylidene difluoride. Compared to other fluoropolymers, it has an easier melt process because of its relatively low melting point of around 177°C.

An extremely hard material, PVDF may be used at temperatures from -62 °C tot 149 °C. Compared to other fluoropolymers, PVDF has a low density (1,78 g/cm³). PVDF has a very good creep resistance that is superior to that of other fluoropolymers. It is unaffected by long-term exposure to sunlight and other sources of ultraviolet radiation. It retains its properties in high vacuum and gamma radiation and is resistant to most acids and alkalis.

PVDF is a specialty plastic material in the fluoropolymer family; it is generally used in applications requiring the highest purity, strength, and resistance to solvents, acids, bases and heat and low smoke generation during a fire event. It is available as piping products, sheet, tubing, films, plate and an insulator for premium wire. It can be injected, molded or welded and is commonly used in the chemical, semiconductor, medical and defense industries, as well as in lithium-ion batteries. Used increasingly in aviation and aerospace applications.
