DuPont™ Kalrez® 8085

DuPontTM Kalrez®8085 perfluoroelastomer parts are a beige, general purpose product for “select” etch, ash/strip and deposition processes. It has been formulated for minimal particle generation in NF3 plasma. Kalrez®8085 exhibits very low particle generation and low weight loss in oxygen and fluorine-based plasmas, has excellent mechanical strength and is well-suited for both static and dynamic sealing applications (e.g., bonded slit valve doors, bonded gate valves, bonded pendulum valves, gas orifice seals, gas feedthrough seals, chamber lid seals, etc.) A maximum continuous service temperature of 240 °C is suggested. Kalrez® 8085 can also withstand short-term excursions to 275 °C. Ultrapure post-cleaning and packaging is standard for all Kalrez® 8085 parts.
