PolyVinylidine DiFluoride, or PVDF is a highly non-reactive and pure thermoplastic fluoropolymer. It is also known as Kynar®. PVDF is very expensive; its use generally reserved for applications requiring the highest purity, strength, and resistance to solvents, acids, bases and heat. It is available as piping products, sheet, plate and an insulator for premium wire. It can be injection molded and welded and is commonly used in the chemical, semiconductor, medical and defense industries.
When poled, PVDF is a ferroelectric polymer, exhibiting efficient piezoelectric and pyroelectric properties. These characteristics make it useful in sensor and battery applications. PVDF has a glass transition temperature (Tg) of about -350 degrees celcius and is typically 50-60% crystalline.
