FEPM Seals for Downhole Applications: Technical Overview
FEPM (Aflas) is worth considering for downhole sealing if you are working with H2S or aggressive chemical environments where standard FKM seals degrade.
Basic specs:
Temperature: -3°C to +230°C
H2S resistant
Three durometer grades available (70, 80, 90 Sh-A)
Better chemical resistance than FKM in harsh conditions
Not a miracle material—just a practical alternative for specific applications. FFKM works better in extreme conditions but costs more. FKM is standard but has limits with aggressive downhole chemistry.
Worth evaluating for your application if you're seeing seal failures in high-temperature or H2S environments. See full technical data. https://www.ismat.in/solution/vertex-elastomers/vertex-a-fepm-aflas-seals/
