Perfluoroalkoxy alkane

This results in materials that are more translucent and have improved flow and creep resistance, with thermal stability close to or exceeding PTFE.

[4] Thus, PFA is preferred when extended service is required in hostile environments involving chemical, thermal, and mechanical stress.

[1] PFA is commonly used as a material for piping and as fittings for aggressive chemicals, as well as the corrosion-resistant lining of vessels in the chemical-processing industry.

[7] PFA is also used to make sampling equipment in analytical chemistry and for geochemical or environmental in situ studies in the field, when it is particularly important to avoid chemical contamination from metallic ions at trace levels.

[10] In 2023, the United States EPA proposed "the first (US national) standard to limit (PFAs) in drinking water;" albeit only six of >12,000 such chemicals were addressed.
