Kalrez® O-rings for Hydrogen Sulfide Removal
Amine units for hydrogen sulfide removal (H2S) at high temperatures use elastomers like Kalrez® Spectrum™ 6380 FFKM parts for resistance to amines. 6380 helps extend MTBR of valves and pumps in amine service.
Sealing Collaboration Pays Dividends in Chamber Cleaning
Chamber cleaning with NF3 / O2 plasma increased maintenance at Spansion due to seal erosion. Kalrez® 9100 parts improved productivity and reduced cost-of-ownership. Kalrez® 9100 parts were successfully qualified in both thin films and dry etch tools.
O-rings for Gas Sweetening Valves
Kalrez® 7090 perfluoroelastomer parts offer an excellent combination of chemical, Rapid Gas Decompression (RGD) resistance , and high temperature resistance for O-ring applications in gas sweetening valves that handle glycol-based solvents.
O-rings in Pressurized Water Reactor
Due to the combination of extreme temperature, pressure and chemical environments, Kalrez® 0090 was used in a series of mechanical seals employed in the operation of boiler feed pumps for pressurized water reactors.
Process Instrument Gaskets
