Why FFKM O-Rings Are Replacing Kalrez® in Critical Applications
2025-07-24
In today's demanding industrial environments - especially within semiconductor, petrochemical, and aerospace sectors—the choice of sealing materials can make or break operational efficiency. FFKM (perfluoroelastomer) O-rings have become a top choice for applications that require extreme thermal, chemical, and plasma resistance. Increasingly, engineers are discovering that high-performance FFKM seals - such as those from fluorosealing (FLS)—can serve as effective and economical alternatives to traditional brands like DuPont™ Kalrez®.
