High fluorine content (~68–70 wt%) delivering exceptional resistance to aggressive fuels, oils, and modern low-sulfur diesel formulations.
Optimized for high-temperature compression set resistance, maintaining sealing integrity up to 200 °C in static applications.
Excellent chemical resistance against polar solvents, lubricants, and automotive fluids including biofuels and synthetic ester-based oils.
Good processability on standard rubber processing equipment, supporting efficient extrusion and moldability for complex profiles.
Low extractables profile suitable for demanding automotive and industrial fluid-handling systems requiring minimal leaching.
Fuel system seals and gaskets for gasoline direct injection (GDI) and turbocharged engines.
High-pressure common rail (HPCR) injector O-rings and valve stem seals.
Transmission and powertrain fluid seals exposed to ATF, CVT fluids, and dual-clutch lubricants.
Under-hood hose linings and diaphragms in emission control systems (e.g., EVAP, SCR).
Static and dynamic seals in industrial hydraulic and pneumatic systems operating with phosphate ester or synthetic lubricants.
