• Uses: Coatings, film, filter cloth, instrument linings, filtration membranes, pump parts and linings and valves. Poly(vinylidene fluoride) is resistant to most acids and alkalies but it is attacked by fuming sulfuric acid. It is soluble in dimethylacetamide but is insoluble in less polar solvents. Copolymers have been produced with ethylene, tetrafluoroethylene, chlorotrifluoroethylene and hexafluoroethylene. The latter is an elastomer called Viton or Fluorel. The homopolymer is used as a chemical resistant coating for steel, for tank linings, hose, and pump impellors. The elastomeric copolymer with hexafluoroethylene when cured with hexamethylenediamine is used as a seal, gasket, 0-ring, tubing, coating and lining. Poly(vinylidene fluoride) is useful in coatings, film, filter cloth, instrument linings, filtration membranes, pump parts, linings and valves. It is also employed as a material for transducers in devices such as headphones, microphones and sonic detectors. It is also essential for piezoelectric and electrostrictive applications. In addition, it is useful for monofilament fishing lines replacing nylon monofilament. It acts as a standard binder used in the production of composite electrodes for lithium ion batteries. It serves as a high grade insulator for wires, nanomaterials and pressure sensors. It is utilized to make filters which are used to prepare samples for high performance liquid chromatography and other advanced analytical techniques.
