PTFE was discovered by DuPont Co. in 1938. Perfluoroalkoxy alkanes (PFA) is a copolymer of hexafluoropropylene and perfluoroethers. It was developed after the discovery of PTFE by the same producer (DuPont Co.). One commonly known PFA formulation is Teflon PFA. PFA has very similar properties to PTFE, though the biggest difference between PTFE

PTFE materials can be continuously used below 260°C. PTFE is attacked by radiation, and degradation in air begins at a dose of 0.02 Mrad. These properties come from the special electronic structure of the fluorine atom, the stable carbon-fluorine covalent bonding, and the unique intramolecular and intermolecular interactions between the fluorinated polymer segments and the main chains.
