In semiconductor manufacturing, FFKM O-rings serve as the primary seals in plasma etching, CVD, and ALD chambers where they face fluorine-based plasmas, NF3, and remote oxygen plasma. These environments destroy Kalrez® competitors within weeks, but premium FFKM grades maintain integrity for thousands of hours, directly impacting wafer yield and reducing costly tool downtime. https://globalsealstech.com/ffkm-seals/
