PTFE Seal Set: Reliable Sealing Solution for Extreme Conditions​

PTFE seal sets are sealing components manufactured from ​pure polytetrafluoroethylene (PTFE)​​ as the core material, designed for high-corrosion, high-temperature, and ultra-clean scenarios.

   ​Core Characteristics​

• ​Corrosion Resistance:
  Withstands strong acids (e.g., aqua regia, hydrofluoric acid), alkalis, and organic solvents; suitable for pH 0–14 environments.
• ​Temperature Tolerance:
  Long-term operational range: ​​-200°C to 260°C​ (short-term exposure up to ​300°C).
• ​High Purity:
  100% pure PTFE material, meeting contamination-free requirements for food, pharmaceutical, and semiconductor industries.
• ​Self-Lubrication:
  Ultra-low friction coefficient (0.04–0.10), reducing mechanical wear.

   ​Typical Applications​

• ​Valve Seals:
  Chemical ball valves, tank truck PV valves.
• ​Pump Components:
  Corrosion-resistant shaft sleeves, metering pump seals.
• ​Semiconductor Equipment:
  Contamination-free seals for ultra-pure fluid delivery systems.
• ​Medical Devices:
  Artificial joint bearings, sterile container seals.

​Note: Selection requires attention to:

• ​Dimensional tolerance​ (±0.025 mm)
• ​Reinforcement modifications​ (e.g., glass fiber filling for enhanced wear resistance).
