CHEMFILM Engineered for Demanding Applications CHEMFILM® PFA Fluoropolymer Film PFAfluoropolymerfilm is manufactured by Saint-Gobain Performance Plastics and Fabrics 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, metallized, or laminated to a wide variety of materials. PFA Type PG (general purpose 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. PFA Type WF (mechanical welding grade) is an ideal economical solution for applications that don’t require high aesthetic standards, such as hot melt adhesive (welding tape) application. PFA WF grade possesses all physical, mechanical, and thermal properties of PFA film while offering up to 25% cost savings. Applications The combination of chemical resistance and high temperature resistance over a wide frequency range make PFA film an ideal component for circuit board fabricators, flat cable, and electrical insulation applications. Product thickness availability from 12.7 pm (.0005”) through 250 pm (0.010”) at widths up to 1,524 mm (60”) offers circuit board designers flexibility in structure design. The high temperature resistance and non-wetting surface of PFA make it an ideal material for use as a high temperature release film or bagging film for composite manufactures. The continuous use temperature of 260°C (500°F) and a melt point of 310°C (590°F) meet the needs of new resin systems requiring a 230°C (446°F) cure temperature.
