PFA (perfluoroalkoxy) has most of the physical and chemical properties of PTFE, but it has less permeation and more than 10 times the flex life. PFA also has outstanding crack and stress resistance and a low coefficient of friction. It can be used in environments where temperatures range from -320° F to 500° F. It also is suitable for hostile environments involving chemical, thermal and mechanical stress. PFA is used widely in the semiconductor industry where excellent electrical properties, high ionic purity and the ability to withstand a wide range of temperatures is essential. Typical applications include valve and pump linings, insulating bushings, nozzles, O-rings, gaskets and release operations. PFA also meets FDA specification 21CFR.177.1550 and is USP Class VI approved.
