Kel-F® - PCTFE (Polychlorotrifluoroethylene)
Key Features
✔ Physical & Mechanical Properties
• Stable performance across extreme temperatures: -400°F to +400°F (-240°C to +204°C)
• Near-zero moisture absorption (<0.01%) with retained mechanical strength at elevated temperatures
• Ultra-low outgassing characteristics suitable for high-vacuum environments
✔ Chemical & Weathering Resistance
• Exceptional chemical resistance to strong acids, alkalis, and organic solvents
• Non-flammable (UL94 V-0 rated) – neither melts nor drips at high temperatures
✔ Electrical Properties
• Superior insulation properties with high dielectric strength for electronic encapsulation
• Outstanding radiation resistance for high-radiation environments (e.g., nuclear facilities)
Key Applications
• Cryogenic valve seals, chemical processing components
• Electronic component encapsulation, ultra-high vacuum systems
• Medical devices (e.g., surgical implant materials)
