For Semiconductor Oxidation, Diffusion, ALD, and LPCVD Applications
DuPont™ Kalrez® 8900 perfluoroelastomer parts are a black product for oxidation, diffusion, ALD, and LPCVD applications. It offers outstanding thermal stability, very low outgassing and excellent (low) compression set properties. Kalrez® 8900 parts exhibit excellent retention of physical properties at elevated temperatures, have excellent mechanical strength and are well-suited for both static and dynamic sealing applications. A maximum application temperature of 325°C (617°F) is suggested. Short excursions to higher temperatures may also be possible. Ultrapure post-cleaning and packaging is standard for all Kalrez® 8900 parts.

Low Outgassing of Kalrez® 8900 parts
The crosslinking structure of elastomeric seals can become damaged as a result of exposure to high heat and temperature spikes. As a result, elastomeric seals can degrade causing outgassing to occur. Outgassing from sealing materials can be absorbed by the exposed substrate and affect the properties of the grown film. Figure 1 shows the outgassing properties of Kalrez® 8900 versus a competitive perfluoroelastomer.
