Kalrez® MS220

DuPont™ Kalrez® MS220 perfluoroelastomer parts are designed for chemical processing and mechanical seals applications where superior chemical resistance and low compression set are critical for successful sealing performance. Kalrez® MS220 continues the DuPont tradition of providing high value in use perfluoroelastomer parts to extend equipment mean time between repair (MTBR), while offering an excellent combination of properties (resistance to steam, acids and bases) at temperatures up to 230 °C (446 °F). It is an effective alternative to other general purpose competitive perfluoroelastomers (see table 2) and is the product of choice for high volume O-rings.
