PCTFE ROD
used for C
ryogenic
Applications
PCTFE(polychlorotrifluorethyene), is the homopolymer of chlorotrifluorethylene. Kel-F, or PCTFE, offers the unique combination of physical and mechanical properties, nonflammability, high optical transparency, chemical resistance, near zero moisture, and excellent electrical properties that cannot be found in other thermoplastic fluoropolymers. It has a useful temperature range of -200 degrees C to +150 degrees.
PCTFE has excellent chemical resistance, radiation resistance, and flammability characteristics. The material has a useful temperature range of -400
°
F to 380
°
F. PCTFE is resistant to cold flow and it has the lowest coefficient of thermal expansion of any unfilled fluoropolymer. These characteristics make it an excellent choice when dimensional stability is critical.
PCTFE is often used for aerospace applications when chemical resistance, a broad operating temperature range, and low flammability are required. It is also extensively used for cryogenic valve applications.
PCTFE IS WIDELY USED FOR:
-
Cryogenic and chemical processing components
-
Seals and gaskets
-
Aerospace valve seats, pump parts, impellers,
diaphragms, and plugs
-
Laboratory instruments
-
Nuclear service/high radiation exposure
-
Liquid oxygen and liquid nitrogen valve linings
PERFORMANCE CHARACTERISTICS:
-
Dimensionally stable, rigid, and resistant
to cold flow
-
Very low gas permeation and outgassing
-
Near zero moisture absorption
-
Excellent chemical resistance
