High resistance to aggressive automotive fluids including modern low-viscosity engine oils, transmission fluids, and biofuels (e.g., E85, B20).
Excellent high-temperature performance with continuous service capability up to 200 °C and short-term resistance to 230 °C.
Outstanding compression set resistance—critical for dynamic sealing applications requiring long-term reliability.
Low-temperature flexibility down to –15 °C, maintaining effective sealing integrity in cold-start conditions.
Good processability on standard rubber processing equipment, including extrusion and injection molding.
Engine valve stem seals and turbocharger hose couplings in high-performance gasoline and diesel powertrains.
Transmission system seals, including clutch piston seals and solenoid valve diaphragms.
Fuel system components such as fuel injector O-rings and fuel rail gaskets exposed to ethanol-blended fuels.
Under-hood fluid handling seals in hybrid and electric vehicle thermal management systems.
Industrial hydraulic and pneumatic seals operating in demanding chemical environments.
