PFA is produced by copolymerization of perfluoroethers and hexafluoropropylene (the monomer used to produce PTFE). The main difference in its structure is that some carbon atoms are linked to a fluoroether group, with an oxygen atom, and not just carbon-fluorines bonds.<\/p>\n
Properties of PFA are very similar to PTFE or FEP. The thermal stability is close to PTFE: PFA has a melting point, at 305\u00b0C, lower than PTFE while still allowing for a large range of applications. PFA also exhibits low friction.<\/p>\n
Just like FEP, PFA is injection moldable and can be directly extruded. This effectively gives more versatility in designing PFA parts.<\/p>\n
PFA tubes are generally more flexible than PTFE tubes, but don\u2019t reach their flexlife. Compared to FEP, PFA offers globally better mechanical properties at high operating temperatures.<\/p>\n
The production of PFA polymer and its transformation are well-known for their low contamination level. Therefore, PFA is often preferred to other fluoropolymers in high purity applications, like the semi-conductor industry or pharmaceutical production.<\/p>\n<\/div>\n
