Kalrez® perfluoroelastomer parts improve sealing for today's processes.
To meet the demand for greater sealing integrity while maintaining process purity, DuPont Performance Elastomers has a family of high-performance perfluoroelastomer sealing materials uniquely suited for pharmaceutical medical manufacturing. Similar to PTFE in cleanliness, heat and chemical resistance, Kalrez® has the resilience and compressive strength that are characteristic of frequently used materials such ethylene propylene polymers (EPDMs), fluroelastomers (FKMs) and silicone rubber.

With its combination of thermal/chemical performance and rubber-like sealing ability, Kalrez® offers the pharmaceutical industry a new level of protection against process contamination and seal failure. Multi-purpose Kalrez® seals increases process and equipment flexibility and may make it possible to standardize on a single seal material for all process environments.

Kalrez® compound #6230 (black) has been developed to meet the unique sealing needs of today's high-speed, fully automated pharmaceutical and biopharmaceutical manufacturing processes. Kalrez® parts are manufactured by DuPont Performance Elastomers to ensure excellent quality, cleanliness and performance. Avoid these common coupling problems by specifying Kalrez® Sanitary Gaskets
