Perfluoroalkoxy (PFA) is a semi-crystalline, fully fluorinated, melt-processable fluoropolymer. It is a modified polymer of polytetrafluoroethylene (PTFE) by introducing an F3CO- group to the PTFE frame structure. PFA has a broad application ranging from biomedical and aerospace to corrosive environments in the chemical industry.

The main performance characteristics of PFA are as follows:

PFA shows comparable mechanical properties as fluorinated ethylene propylene (FEP) below 200 °C, and performs comparable mechanical properties as PTFE above 200 °C.
The thermal stability of PFA is almost the same as that of PTFE and better than that of FEP.
Compared with PTFE, PFA film has better transparency.
Since PFA is perfluorinated like FEP, it retains high chemical resistance, low surface energy and good electrical insulation properties.
PFA is unaffected by prolonged exposure to direct sunlight, wind, rain and exhaust gases.
