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 and plate. It can be injection molded and welded and is commonly used in the chemical, semiconductor and medical industries.


PVDF is a ferroelectric polymer, exhibiting efficient piezoelectric and pyroelectric properties. These characteristics make it useful in sensor and battery applications. In physics, the ferroelectric effect is an electrical phenomenon whereby certain ionic crystals may exhibit a spontaneous dipole moment. ... Piezoelectricity is the ability of certain crystals to produce a voltage when subjected to mechanical stress. ... Pyroelectricity is the electrical potential created in certain materials when they are heated. ... A sensor is a technological device or biological organ that detects, or senses, a signal or physical condition and chemical compounds. ... Four double-A (AA) batteries In science and technology, a battery is a device that stores energy and makes it available in an electrical form. ...

PVDF can be dissolved in polar solvents such as organic esters and amines.
PVDF components are used extensively in the high purity semiconductor market (low extractable values), pulp and paper industry (chemically resistant to halogens and acids), nuclear waste processing (radiation and hot acid applications), the general chemical processing industry (chemical and temperature applications), and water treatment membrane (industrial and potable water use).
PVDF homopolymers and copolymers have gained success in the battery industry as binders for cathodes and anodes in lithium-ion technology, and as battery separators in lithium-ion polymer technology.
