1,1-Difluoroethylene - Wikipedia
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.
Polyvinylidene fluoride - Wikipedia
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.

Vinylidene group - Wikipedia
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.
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
Vinylidene Fluoride - an overview | ScienceDirect Topics
Vinylidene fluoride (VDF), CH 2 =CF 2, is flammable and is a gas at room temperature. Physical properties of vinylidene fluoride are presented in Table 3.1. It is colorless and almost odorless and boils at −84°C. Vinylidene fluoride can form explosive mixtures with air.

Vinylidene Fluoride | Encyclopedia MDPI
2020年10月30日 · VDF is the second largest product among fluorocarbons with an annual production capacity of above 53,000 tons. The demand for VDF is increasing rapidly. At present, in industry, VDF is usually produced via the dehydrochlorination of 1,1-difluoro-1-chloroethane (HCFC-142b) at reaction temperatures above 650 °C. 1. Introduction.
