Material Properties​

• 100% Virgin Polytetrafluoroethylene (PTFE)
• Resists strong acids (Aqua regia, HF acid), alkalis (pH 0-14)
• Operating temperature: ​​-200°C to 260°C​ (short-term ​300°C)

​Engineering Advantages​

• Fits ​DN200–5000mm​ flange dimensions
• Supports ​U-folded envelope/composite structures​ (prevents cold flow deformation)
• Zero contamination (Pharma/Food-grade certifications)

​Key Applications​

• Reactor/storage tank sealing
• Oil & gas pipeline interfaces
• Acid-washing towers/exhaust gas treatment
• Pharmaceutical sterile systems

​Selection Guide:

• For ultra-high pressure (>4 MPa): ​Graphite-filled PTFE​
• For vibration environments: Prioritize ​waveform structures​

Terms strictly follow ISO/ASME standards: "virgin PTFE" (unmodified material), "aqua regia" (chemical term), DN (nominal diameter). Industrial abbreviations (HF, pharma) retained.
