1,1-Difluoroethylene

Chemical compound

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.
