PFA has the advantage to withstand a higher continuous working temperature compared to FEP. Due to melt processability, PFA can be extruded in longer continuous lengths than PTFE. Note: The chemical resistance of each polymer is mainly determined by the chemical structure of the material and the strength of the weakest link in this specific structure.

The pressure rating for the fully annealed SS316 tubing, OD = 1.500" and Wall thickness = 0.065" is 1,500 psi. (See the inch tube pressure rating table on this page). The temperature derating factor and severity of service derating factors are 0.81 and 0.67, respectively. The maximum design pressure = 1,500 x …
Even in critical melting point (service temperature) ratings, both materials have identical properties. In fact, they differ significantly only with regard to cold flow (PFA better than PTFE) and folding endurance (PTF E better than PFA). PFA has a higher creep resistance but PTFE can withstand a higher degree of multiple folding. References
The TC4 ProFlex™ PFA offers very long lengths up to 1,000 feet, excellent chemical resistance, and flexibility. PFA has the same chemical and temperature resistance as PTFE and much better flex life than FEP. ProFlex industrial grade PFA was designed for customer appliions that don''t require or need pharmaceutical grade hose.
Perfluoroalkoxy alkanes (PFA) are fluoropolymers.They are copolymers of tetrafluoroethylene (C 2 F 4) and perfluoroethers (C 2 F 3 OR f, where R f is a perfluorinated group such as trifluoromethyl (CF 3)).The properties of these polymers are similar to those of polytetrafluoroethylene (PTFE). Compared to PTFE, PFA has better anti-stick properties and higher chemical resistance, at the expense
PFA is also one of the few plastics that is both suitable for high and low temperature appliions and can be used over the range of temperatures -268°C to 260°C. This is very similar to the working temperature range of PTFE but PFA has the advantage of being melt-processable.

High-Temperature PTFE PipeNipples and Pipe for Chemicals. This PTFE pipe can withstand a wider temperature range than any of our other plastic pipe for chemicals. It is commonly used in high-purity chemical flow processes, such as semiconductor and clean room appliions.
The main difference between perfluoroalkoxy alkane (PFA) and PTFE is PFA is a polymer with the ability to be melt-processed. Its structural difference results in improved flow, thermal stability, and creep resistance. PFA resists stress cracking and attack by almost all chemicals and solvents. PFA is temperature resistant, making it ideal for

viscosity of PFA is over a million times lower than that of PTFE. PFA offers the highest temperature rating and broadest chemical resistance of any melt-processible fluoropolymer, making it ideal for extreme chemical and thermal environments. PFA is similar to FEP in many ways but in general has better mechanical properties at higher temperatures.
Continuous service temperature above 260 °C (500 °F) may be feasible, depending on such factors as chemical exposure, support from the substrate, etc. When considering uses of Teflon™ PFA fluoropolymer resins above 260 °C (500 °F), preliminary testing should be done to verify suitability.
