Poly(vinylidene fluoride) (PVDF) is made by the polymerization of vinylidene fluoride in aqueous medium under pressure but details of the process have not been disclosed. Two grades of polymer are available with differing average molecular weight, namely 300000 and 600000. Poly(vinylidene fluoride) has good tensile and impact strengths. The polymer has unusual piezoelectric and pyroelectric properties which have resulted in its use in solid state switching devices.
The resistance of poly(vinylidene fluoride) to solvents and chemicals is generally good but inferior to that of polytetrafluoroethylene and polychlorotrifluoroethylene. Some highly polar solvents such as dimethylacetamide dissolve the polymer at elevated temperature whilst organic amines cause discoloration and embrittlement. Fuming sulphuric acid leads to suiphonation. Poly(vinylidene fluoride) has good heat resistance and may be used continuously at temperatures up to 150°C. The polymer may be melt processed by the standard techniques of injection moulding and extrusion. The polymer has very good weather resistance. Applications for poly(vinylidene fluoride) include moulded and lined tanks, valves, pumps and other equipment designed to handle corrosive fluids. The polymer is also used in coatings and wire covering.
