Vinylidene Chloride
Vinylidene Chloride its chemical name is 1,1-dichloroethylene, a colourless, dense, toxic, volatile, flammable liquid belonging to the family of organic halogen compounds.
1, 1-Dichloroethene is an industrial chemical solvent having sweet smell. It is also called vinylidene chloride. 1, 1-Dichloroethene is used to make certain plastics, such as flexible films like food wrap, and in packaging materials.
Vinylidene Chloride is non soluble in water and soluble in organic solvent.
Uses
Vinylidene chloride is used as an intermediate for organic chemical synthesis.
Vinylidene chloride is also used in the production of polyvinylidene chloride copolymers. The major application of these chloride copolymers is in the production of flexible films for food packaging.
These copolymers are also used extensively in many types of packing materials, as flame retardant coatings for fiber and carpet backing and in piping, coating for steel pipes, and adhesive applications.

Vinylidene Chloride (VDC)
Vinylidene chloride, also called 1,1-dichloroethylene, a colourless, dense, toxic, volatile, flammable liquid belonging to the family of organic halogen compounds, used principally in combination with vinyl chloride, acrylonitrile, or methyl methacrylate for the manufacture of a class of plastics called saran. Vinylidene chloride is also used as a starting material for making methylchloroform, or 1, 1, 1-trichloroethane, and a solvent useful in cleaning electrical machinery.
