PVF film is a fluoropolymer film that we can supply in a range of sizes and thicknesses. It has unique properties like high dielectric strength, chemical inertness and heat resistance. These versatile fluoropolymer films have applications in electrical insulation, chemical containers, wire coatings, and protective barriers where durability and chemical resistance are needed. Thanks to our wide range of PVF films, we can provide the right option for engineers and researchers developing products and processes involving aggressive chemicals or high temperatures.
