Chemraz ® XCD, a perfluoroelastomer, is specifically designed to exceed the most rigorous demands of front-end semiconductor thermal processing equipment. Chemraz ® XCD withstands the extreme thermal challenges typically found in LPCVD (low pressure chemical vapor deposition), RTP (rapid thermal process), and epitaxial deposition systems.

Because of its unique polymer and filler structure, Chemraz ® XCD provides the lowest compression set at high operating temperatures (> 572°F/300°C) of any perfluoroelastomer on the market, resulting in increased seal integrity and longer seal lifetimes. This means reduced downtime and higher wafer processing yields.

With the lowest outgassing profile for perfluoroelastomer materials in high-temperature applications, Chemraz ® XCD provides a cleaner process environment. Because of its reduced surface stiction, Chemraz ® XCD can be used for semi-dynamic and static sealing applications. Chemraz ® XCD remains stable at operating temperatures up to 572°F (300°C) while maintaining exceptional compression set.
