High fluorine content (~68 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 at elevated temperatures up to 200 °C for extended service life.
Good processability in standard rubber compounding equipment, including internal mixers and extruders.
Outstanding resistance to modern biofuels (e.g., E85, B20) and low-sulfur diesel formulations.
Fuel system components: O-rings, gaskets, and diaphragms for automotive and aerospace fuel handling.
Under-hood sealing solutions: Valve stem seals, turbocharger hoses, and coolant circuit gaskets.
Chemical processing equipment: Linings, pump diaphragms, and valve seats exposed to corrosive media.
Oil & gas downhole tools: Seals and packer elements operating in high-temperature, high-pressure hydrocarbon environments.
Industrial hydraulic systems requiring long-term stability in phosphate ester-based fire-resistant fluids.
