Excellent resistance to aggressive automotive fluids including biofuels, synthetic lubricants, and high-temperature transmission oils.
Outstanding thermal stability with continuous service capability up to 200 °C in demanding dynamic sealing environments.
Superior chemical resistance to acids, bases, amines, and polar solvents commonly encountered in industrial processing.
Low compression set retention ensures long-term sealing integrity under prolonged stress and elevated temperatures.
Good processability for conventional rubber processing equipment, including extrusion and compression molding.
Automotive fuel and oil system seals (e.g., fuel injector O-rings, turbocharger hose liners).
Chemical processing equipment gaskets and diaphragms exposed to corrosive media.
Aerospace hydraulic system components requiring wide temperature and fluid compatibility.
Oil & gas downhole elastomeric parts operating in H₂S-rich, high-pressure, high-temperature (HPHT) environments.
Pharmaceutical and food-grade sanitary seals where regulatory compliance and purity are critical.
