Sealing material information
DuPont™ Kalrez® 0090 - FFKM Perfluoroelastomer = RU21™ - Machined by Seal Engineering AS
We offer machined seals in Kalrez® 0090 and other FFKM-compounds with unrivaled delivery time for standard and custom seals.
RU21™ has a broad chemical resistance and temperature resistance up to 250° C. RU21™ can typically be used in highly aggressive chemical processing, semiconductor wafer processing, pharmaceutical or aerospace applications.
In addition, with the certifications mentioned below RU21™ is a natural choice for applications in the oil and gas industry within the temperature envelope of -21° C to +250° C (conditional).
- RU21™ meets the requirements of the NORSOK M-710 standard (Rev.2, October 2001) with respect to sour fluid ageing resistance.
- RU21™ meets the requirements of the NORSOK M-710 standard (Rev.2, October 2001) with respect to rapid gas decompression (RGD) resistance at 150 barg and 100°C.
