Polyvinylidene fluoride or polyvinylidene difluoride (PVDF) is a highly non-reactive thermoplastic fluoropolymer produced by the polymerization of vinylidene difluoride. Its chemical formula is (C 2 H 2 F 2) n. PVDF is a specialty plastic used in applications requiring the highest purity, as well as resistance to solvents, acids and hydrocarbons.

1,1-Difluoroethylene, also known as vinylidene fluoride, is a hydrofluoroolefin. This colorless, flammable gas is a difluorinated derivative of ethylene. Global production in 1999 was approximately 33,000 metric tons. [3] It is primarily used in the production of fluoropolymers such as polyvinylidene fluoride and FKM.

In chemistry, vinylidenes are compounds with the functional group C=CH 2. An example is 1,1-dichloroethene (CCl 2 =CH 2) commonly called vinylidene chloride. It and vinylidene fluoride are precursors to commercially useful polymers.

1,1-Difluoroethylene (or vinylidene fluoride) is a colorless gas which is flammable in the ranges of 5.5 to 21%. It is toxic by inhalation and contact. It is slightly soluble in water and soluble in alcohol and ether.

Vinylidene fluoride (VDF) is a colourless, odourless, flammable gas that is sparingly soluble in water. It is used mainly in the manufacture of VDF polymers, and with chlorotrifluoroethylene

Polyvinylidene Fluoride, known by its acronym PVDF, is a high-performance thermoplastic material renowned for its robust chemical resistance, thermal stability, and physical durability. A unique member of the fluoropolymer family, it consists of a polymer chain of carbon atoms, to which two fluorine atoms and one hydrogen atom are attached.

Polyvinylidene fluoride (PVDF) is known as a favorite polymer from the family of fluoropolymers due to its excellent piezoelectric properties, thermal stability, and mechanical strength.
