High fluorine content (~68–70 wt%) for exceptional resistance to aggressive chemicals, including amines, ketones, and polar solvents.
Optimized low-temperature flexibility with a glass transition temperature (Tg) of approximately –15 °C, enabling reliable sealing performance in cold-start conditions.
Excellent compression set resistance after prolonged exposure to elevated temperatures up to 200 °C.
Good processability on standard rubber mixing and extrusion equipment, supporting efficient high-volume manufacturing.
Low extractables profile, meeting stringent requirements for automotive fuel and lubricant systems.
Dynamic and static seals in high-pressure common-rail diesel fuel injection systems.
O-rings and gaskets for turbocharger oil supply lines and EGR cooler components.
Valve stem seals and injector cup seals in modern gasoline direct injection (GDI) engines.
Sealing elements in transmission control modules exposed to synthetic ATF fluids.
Fuel system components requiring compliance with SAE J2045 and ISO 6945 standards.
