Kalrez® Compression Set Resistance and Sealing Force Retention
Kalrez® perfluoroelastomer parts last longer and seal more effectively than other elastomers due to their exceptional heat resistance. Longer-lasting seals can be a direct route to extended mean time between replacement and lower cost of ownership.
Compression set most often causes issues in applications that undergo broad thermal cycling. When a perfluoroelastomer
