Comparison with FKM highlights FFKM's advantages in universal chemical resistance and higher temperature limits. While FKM suffices for many hydrocarbon and oil applications economically, FFKM handles ethers, ketones, amines, and strong oxidizers where FKM degrades. Thermal ceiling differences—FKM around 200-250°C versus FFKM over 300°C—dictate selection in extreme heat. Cost differen... https://globalsealstech.com/ffkm-seals/
