High fluorine content (~68–70 wt%) delivering exceptional resistance to aggressive fuels, oils, and chemicals.
Optimized low-temperature flexibility with a glass transition temperature (Tg) of approximately –15 °C.
Excellent compression set resistance after prolonged exposure to elevated temperatures up to 200 °C.
Good processability in standard rubber mixing and molding equipment, including injection and compression molding.
Outstanding resistance to modern low-sulfur diesel, biofuels (e.g., FAME), and automotive lubricants meeting ACEA and OEM specifications.
Fuel system components: O-rings, gaskets, and seals for high-pressure common rail diesel injectors.
Under-hood automotive sealing: Valve cover gaskets, turbocharger hose couplings, and EGR system seals.
Aerospace fluid handling systems: Hydraulic and fuel line seals requiring FAA-compliant elastomer performance.
Industrial chemical processing: Diaphragms, valve seats, and pump seals exposed to aromatic hydrocarbons and polar solvents.
Oil & gas downhole tools: Seals for drilling equipment operating under high temperature and sour gas (H₂S/CO₂) conditions.
