Polyvinylidene fluoride is a specialty plastic material in the fluoropolymer family. It is used generally in applications requiring the highest purity, strength, and resistance to solvents, acids, bases and heat and low smoke generation during a fire event. Polyvinylidene fluoride is made up of 59% fluorine, 38% carbon and 3% hydrogen. The compatibility of the carbon and fluorine is such that it offers resistance to UV degradation and atmospheric chemical attach, which is far superior to the acrylic topcoat. PVDF is the material of choice when the porous structure will be exposed to ozone or chlorine. A fine powder grade is also used as the principal ingredient of high-end paints for metals. PVDF is known particularly for its creep resistance over a broad range of temperatures. It is widely used for gasketing and the lining of pipes and tanks. Its highly desirable solubility and electrical properties result from the polarity of alternating CH2 and CF2 groups on the polmer chain. PVDF tubing is ideal for fluid applications which require a high degree of purity such as the transfer of ultra-pure deionized water. Thinner walled PVDF tubing is translucent making it easier to confirm fluid movement. Thin wall PVDF tubing is also more flexible than FEP and PFA tubing but does not have as broad a working temperature range. If one needs a polymer that will withstand exposure to harsh thermal, chemical or ultraviolent conditions, PVDF offers superior stability similar to the performance of fluoropolymers in these environments. PVDF, an extremely hard material, may be used at temperatures from -80Â°F to 300Â°F (â€“62Â°C to 149Â°C). No oxidation of thermal degradation occurs during continuous exposure to 300Â°F (149Â°C). PVDF is a fluorocarbon and is classified as â€œSelf Extinguishing, Group 1 by Underwriters Laboratories, Inc. Thus it is used as good anti-corrosion material in chemical industry, especially in the circumstances of acid, organic solvents, halogens, as well as their mixture. Widely used as insulation material in electronic / electric industries, computer industry, air/space industry to make cable sheathing, coating layer, and condenser film, etc. PVDF may be synthesized from the gaseous VDF monomer via a free radical (or controlled radical) polymerization process. This may be followed by processes such as melt casting, or processing from a solution (e.g. solution casting, spin coating, and film casting).At present, Vinylidene fluoride/Polyvinylidene Fluoride resin is not produced in India. A number of Indian organisations who need to use PVDF in pumps, membranes, electronic parts either import the PVDF product itself or import PVDF sheet/powder for the production of PVDF product. PVDF sheets and rolls are imported in various thickness and sizes depending upon the requirement of individual organizations. The use of PVDF membrane is very selective in India and is imported. Indian demand for PVDF is much less than potential. There is a considerable efforts put forward to increase the demand for PVDF in India by setting up application laboratories and carrying out strong technical services oriented market campaign.
