PFA-PG General Purpose Film
PFA-PG, general purpose fluoropolymer film is manufactured by Saint-Gobain Specialty Films from perfluoroalkoxy (PFA) polymer resin. This film offers the highest continuous use temperature 260°C (500°F) of any melt-processable fluoropolymer film, PFA film offers many of the performance properties of PTFE in a clear, transparent form and can be heat sealed, thermoformed, welded, metalized, or laminated to a wide variety of materials. Saint-Gobain's PFA film offers a combination of excellent dielectric properties across a wide temperature and frequency range, the highest level of chemical and stress crack resistance, excellent clarity and weatherability. The chemical resistance of PFA provides excellent tank-lining performance.
