Kalrez® Spectrum™ 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® Spectrum™ 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.

Kalrez® Spectrum™ 7090 Features & Benefits
Product Highlights
- Higher hardness and modulus.
- Exceptional thermal stability and compression set resistance.
- Outstanding seal force retention properties and response to temperature cycling effects.
- Excellent mechanical properties.
- Lower coefficient of thermal expansion (CTE) versus other Kalrez® parts thus minimizing the need to increase the free volume of the seal gland when upgrading from fluoroelastomers (FKM) to perfluoroelastomers (FFKM)
- Kalrez® Spectrum™ 7090 is a product for uses requiring higher hardness/higher modulus than more typical applications.
- Kalrez® Spectrum™ 7090 perfluoroelastomer parts are well suited for both static and dynamic applications as well as specific sealing applications requiring extrusion resistance at high temperatures.
- These specialty black parts have excellent thermal and mechanical properties, including excellent compression set and seal force retention, resistance to temperature cycling effects, and rapid gas decompression (RGD). Short excursions to higher temperatures may also be possible.
