Combining the best of PTFE and FEP, PFA was developed in the late 1960äó»s in response to a need for a resin with chemical and use temperatures closer to PTFE while retaining the conventional melt processability of FEP. While slightly more expensive, it carries a number of improvements over other fluoropolymers.
The modifier used in PFA resins results in the same maximum use temperature and chemical inertness as PTFE (500 F). But PFA tubing also has higher working pressures than FEP and PTFE. In very aggressive industrial environments, such as hydrofluoric and nitric acids at 250 F, PFA tubing is preferred and has proven to provide a long service life.
Manufactured by Fluorotherm in the USA, it is transparent in color and and USP Class VI, NSF and FDA approved.
