Perfluoroether rubber (FFKM) is a fluororubber that does not contain any C-H bonds. Only perfluoroether rubber can adapt to harsh conditions such as medium corrosion, high temperature, high pressure, and radiation environment.
| Advantage Category | Details |
|---|---|
| Extreme Temperature Resistance | – Operational range: -20°C to +327°C (short-term 350°C) |
| – Retains elasticity and sealing performance at high temperatures | |
| Universal Chemical Resistance | – Resistant to >1.800 chemicals, including: |
| – Strong acids (e.g., H₂SO₄, HNO₃), bases (e.g., NaOH) | |
| – Organic solvents (e.g., toluene, acetone), ketones, and amines | |
| – Oxidizing agents (e.g., O₃, Cl₂) and plasma environments | |
| Low Compression Set | – <15% compression set after 70h at 300°C (ASTM D395) |
| – Ensures long-term sealing integrity in dynamic applications | |
| Mechanical Performance | – Tensile Strength: 10–25 MPa (superior to FKM/EPDM) |
| – Hardness (Shore A): 60–90 (customizable for specific applications) | |
| Plasma/Radiation Resistance | – Withstands >1.000 kGy radiation exposure (gamma/electron beam) |
| – Ideal for semiconductor and nuclear applications | |
| Regulatory Compliance | – FDA 21 CFR 177.2600 (food/medical contact) |
| – USP Class VI, ISO 10993 (biocompatibility) | |
| Service Life | – 5–10× longer lifespan vs. FKM/FKM in aggressive media |
| – Reduces maintenance cycles and downtime | |
| Low Extractables/Leachables | – <0.5% weight loss in solvent extraction tests (critical for pharmaceutical/semiconductor purity) |
| Environmental Stability | – UV/ozone resistant; minimal degradation in outdoor exposures |
