DuPont™ Kalrez® 8575

DuPont™ Kalrez® 8575 perfluoroelastomer parts are a white product for oxidation, diffusion, lamp anneal and RTP sealing applications. Kalrez® 8575 exhibits excellent thermal stability and long-term sealing performance, less Infrared (IR) absorption and significantly reduced outgassing properties at elevated temperatures. It also has good mechanical properties and is well-suited for both static and low stress/low sealing force applications. A maximum application temperature of 300°C (572°F) is suggested. Ultrapure post-cleaning and packaging is standard for all 8575 parts.

Key Performance Features Contribute to Extended Seal Life

• White color reduces IR absorption and reduces seal temperature
• Very low outgassing properties
• Excellent (low) compression set properties
• Excellent elastic recovery properties

Suggested Applications

• Chamber lids
• Gas inlets

Seal Force Retention/Compression Set

IR Absorption vs. Seal Temperature

In RTP processes, IR light is used to heat the wafer. The amount of IR light absorbed by the seal is influenced by color. White seals like Kalrez® 8575 will absorb less IR light than black seals. As a result, the effects of thermal aging on white seals will be reduced throughout the life of the seal.
