Polychlorotrifluoroethylene (PCTFE) Products​ are high-performance industrial components made from the specialty fluoroplastic Polychlorotrifluoroethylene (PCTFE). PCTFE integrates the following core properties:

  Extreme Performance​

• ​Temperature Resistance:
  Long-term service: ​​-196°C to 125°C; short-term tolerance up to ​150°C​ (e.g., liquid nitrogen environment seals).
• ​Corrosion Resistance:
  Resists aqua regia, hydrofluoric acid, alkalis, and organic solvents (except concentrated sulfuric acid); stable under high-pressure steam.
• ​Functional Properties:
  High transparency (90% light transmittance), exceptional gas barrier properties (ultra-low water vapor permeability), UL94 ​V-0 flame retardancy​ (self-extinguishing, non-toxic).

   ​Core Application Areas​

• ​Chemical Corrosion Protection:
  Reactor linings, corrosion-resistant pumps/valves (replaces metal parts in strong acid transport).
• ​Electronic Encapsulation:
  High-frequency communication components, semiconductor wafer carriers (zero ion leaching, low dielectric loss).
• ​Medical & Scientific Research:
  Transparent observation windows, cryogenic labware (bio-inert, withstands -196°C deep-freeze).
• ​New Energy & Aerospace:
  Fuel cell seals, spacecraft cryogenic sealing rings (anti-creep, high-pressure resistant).

   ​Processing Advantages​

Formed via ​injection molding​ (250–320°C), ​extrusion, or ​compression molding. Enables manufacturing of:

• ​Precision gears, ​transparent films, and ​complex profiled parts, meeting demands for high dimensional stability and extreme-environment endurance.
