DuPont™ Kalrez® perfluoroelastomer parts last longer and seal more effectively than other elastomers due to their exceptional chemical resistance. Kalrez® parts can withstand attack by more than 1,800 chemicals, including many acids and amines that cause other elastomers to fail due to excessive swelling.
Kalrez® parts have exceptional heat resistance even after long-term exposure to temperatures up to 327°C. Kalrez® retains its elasticity and recovery properties better than other high-temperature elastomers. There are many Kalrez® products developed for specific processing environments.
For more information on the performance of specific compounds please refer to datasheets or review compounds suggested in market literature or, you may request a downloadable copy of the Kalrez® Application Guide or see the General Chemical Resistance Guide.
