DuPont™ Kalrez® Spectrum™ 7090

DuPontTM Kalrez® SpectrumTM 7090 perfluoroelastomer parts are specifically targeted for use in applications requiring high
hardness/higher modulus properties. These specialty black parts have excellent mechanical properties including compression set
resistance, seal force retention, response to temperature cycling effects and rapid gas decompression resistance. Kalrez® SpectrumTM
7090 perfluoroelastomer parts are well suited for both static and dynamic sealing applications, especially applications that require
extrusion resistance at higher temperatures. They also offer outstanding thermal stability and chemical resistance. A maximum service
temperature of 325 °C (617 °F) is suggested. Short excursions to higher temperatures may also be possible.
