Sign in to saveAlso known as Difluoro-1,1-ethylene, 1,1-Difluoroethene, Halocarbon 1132A, VDF, Vinylidene difluoride, 1,1-difluoroethylene
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. It is primarily used in the production of fluoropolymers such as polyvinylidene fluoride and FKM.
