Vinylfluoride polymer

Polyvinyl Fluoride. See Vinylfluoride Polymer in this Section... 

Vinylfluoride Polymer (Poly vinyl Fluoride), (—HgC.CHF—). A transparent solid used for prepn of films. It possesses superior resistance to chemicals and outdoor weather. The film is flexible, tough, has dielectric constant, has low permeability to air Si water a d has high resistance to heat. This polymer may serve as replacement of paints and as an outdoor protective coating for siding roof also br glazing, packaging, and electrical uses... 

Ferroelectric properties (much weaker than PVF2) are shown also by other polymers like poly(vinylchloride) (PVC) or poly(vinylfluoride) (PVF). (See Table 48.3 for... 

These nebulizers and their components are typically constructed from polymer materials, such as polytetrafluoroethylene (PTFE), perfluoroalkoxy (PFA), or poly-vinylfluoride (PVF), although some designs are available in borosilicate glass or quartz. The excellent corrosion resistance of the polymer nebulizers means they have naturally low blank levels. This characteristic, together with their ability to handle small sample volumes found in applications such as vapor phase decomposition (VPD), makes them an ideal choice for semiconductor laboratories that are carrying out ultratrace element analysis. - A microflow concentric nebulizer made from PFA is shown in Figure 3.8, and a typical spray pattern of the nebulization process is shown in Figure 3.9.
