PCTFE

Polychlorotrifluoroethylene

PCTFE is well suited for cryogenic parts such as ball valve seats & seals. APT typically molds and machines the Daikin Neoflon M-400H grade of PCTFE.

PCTFE is a tough, durable fluoroplastic that exhibits unique physical and mechanical properties:

• Stress-crack resistance
• High mechanical strength and low shrinkage rate at low temperatures providing excellent stability for valve seats.
• Excellent stability at low temperatures
• Good machining properties
• Excellent chemical resistance to all inorganic corrosive liquids
• Practically zero moisture absorption
• Excellent electrical properties maintained in high humidity conditions
• Maximum temperature for continuous use: 248 F (120 C)
• Melting point: Approx. 410 F
• These characteristics are maintained over a working range of
  -400 deg. F to 248 deg. F (-240 deg. C to 120 deg. C).

PCTFE M-400H Material Properties:

Compressive Strength (D-695): 5000-5500 psi
Tensile Strength (D-638): 4800-5300 psi
Elongation: 100 – 200%
Flexural Strength (D-790): 9000 – 10,000 psi
Hardness, Shore D: D90

Properties listed are general ranges. Actual properties may vary based on material lot and processing.
