With a service temperature range up to 327°C, Kalrez elastomers provided by Fluid Seals retain their elasticity and recovery properties even after long term exposure.
ISO 3384 have proven the performance of Kalrez elastometers when it comes to sealing force retention. Even under harsh and aggressive conditions, these seals will retain their sealing force, and due to their true-rubber resiliency, will prevent leaks caused by creep.
These seals exhibit low compression set, maintaining their elastic recovery to maintain tight seals over extended periods of time.
Because Kalrez parts recover better under compression than other perfluoroelastomers, they maintain their shape better under prolonged stress, making them appropriate for a range of high temperature and harsh chemical applications.
