Polyvinylidene chloride.

Polyvinylidene chloride (PVDC).

Polyvinylidene chloride (PVDC) is a synthetic resin.
It is produced by the polymerisation of vinylidene chloride.

Polyvinylidene chloride.
It has a remarkable barrier against water and oxygen.
It has a superior chemical resistance to alkalies and acids.
It is insoluble in oil and organic solvents. But it is soluble in polar solvents.
It is impervious to mold, bacteria and insects.
PVDC film is mainly used in packaging of food,drugs, cosmetics etc.
It is also used to make tapes.
It is used to make doll hair.
It is used in shoe insoles.
