Introduction

Product Introduction:

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
