Excellent resistance to aggressive chemicals including strong acids, bases, and polar solvents.
Outstanding high-temperature performance with continuous service capability up to 230 °C.
Low compression set retention, ensuring long-term sealing integrity under dynamic conditions.
Good processability for extrusion and compression molding—compatible with standard fluoroelastomer equipment.
Enhanced resistance to automotive fuels and biofuels (e.g., E85, biodiesel) versus conventional FKM grades.
Automotive fuel system components: injector O-rings, fuel rail gaskets, and pump seals.
Chemical processing equipment: valve seats, diaphragms, and liner seals exposed to corrosive media.
Aerospace fluid handling systems: hydraulic seals and fuel-resistant hose linings.
Oil & gas downhole tools: packer elements and blowout preventer (BOP) elastomeric parts.
Semiconductor manufacturing: seals and gaskets in wet etch and cleaning tool environments.
