PCTFE - Molded & CNC machined parts including valve seats and end caps

PCTFE:



A tough, durable fluoroplastic that exhibits unique physical and mechanical properties:

  • nonflammability
  • high optical transparency
  • excellent chemical resistance to all inorganic corrosive liquids
  • practically zero moisture absorption
  • excellent electrical properties

These characteristics are maintained over a working range of
-400 deg. F to +400 deg. F  (-240 deg. C to +204 deg. C).

Material Properties:
  • Compressive Strength: 5000-5500 psi
  • Tensile Strength: 4800-5300 psi
  • Elongation:  150%
  • Hardness, Shore D:  D90
The commonly known Kel-F® brand of PCTFE, a registered trademark of 3M,
is no longer manufactured. APT typically processes PCTFE, M-400H grade, by Daikin America.

Note: The property data offered represents average values obtained on laboratory test samples. Values listed are high limits. Properties may vary based upon processing technique and temperature. Data should be used only as a guide in selecting the appropriate compound. Actual performance will be affected by processing methods as well as end use service conditions.
