Perfluoroelastomer (FFKM/FFPM) parts resist over 1,800 different chemicals, including concentrated nitric acid, sodium hydroxide, ethylene diamine and steam while offering the high temperature stability of PTFE (327°C).
FKM parts and seals also help prevent semiconductor process contamination by reducing particulates, lowering extractables, and resisting degradation in harsh plasma. Perfluorelastomers provide low outgassing in vacuum-sealing applications. FDA-compliant seals are also available for food, beverage or pharmaceutical processes.
FFKM parts are used in highly aggressive chemical processing, semiconductor wafer fabrication, pharmaceutical, oil and gas recovery, and aerospace applications. The long-term, proven performance of FFKM parts can mean less frequent seal changes, repairs and inspections, increasing process and equipment uptime for greater productivity and yield.
